I also have a tendency to overuse semicolons; in my post, I used even more of those than I did ellipses. I often tend to over-use hyphens, as well - though I don't seem to have suffered that flaw this time. (I also use many more brackets than most people (including nested ones), which some people find a bit off-putting.)
At least a tad more seriously: English only has so many forms of punctuation to transition from one thought to the next, each of which has a somewhat different subjective flavor. I started reading early enough that I sometimes claim that the deep structures of my brain grew to incorporate more textual elements than verbal ones; each time I use an ellipsis instead of a period (or hyphen, or semicolon, or etc), it's generally because the thoughts I'm trying to express feel, to me, as if the transition is more like that of an ellipsis than anything else.
I do try to remember to make at least one sweep through anything I write for editing, after I write the first draft; but, though people have occasionally commented on my textual idiosyncrasies, this is the first time I recall in which they've been described as distracting. I'm certainly willing to adjust my writing style in order to more effectively get across my points... but as I re-read my post, considering each ellipsis, they read to me as inserting something very much like a verbal pause, in order to emphasize the difference between what comes before and after - a pause greater than a comma, but not quite enough to break apart into separate sentence fragments. A semicolon isn't quite appropriate; the sentence still continues, grammatically no more interrupted than with a comma. A hyphen could certainly work, though I tend to think they're better used as minor brackets.
Do you have any particular/concrete suggestions, other than 'use less ellipses'?
My true rejection of ellipses is that I associate overuse of ellipses with conspiracy theory-style writing (e.g. "you might think that Obama isn't a lizard-person... but you'd be wrong!"). It reads to me like overconfidence in the shock value of your insights. You might decide not to care that I think this, but I don't think I'm alone in having this association.
Here are more specific suggestions about how I would replace each of your uses of ellipses.
...The reason I'm posting about this book here... is that it's giving me some new perspectives
I'm about a third of the way through "Debt: The First 5,000 Years" by David Graeber, and am enjoying the feeling of ideas shifting around in my head, arranging themselves into more useful patterns. (The last book I read that put together ideas of similar breadth was "Economix: How and Why Our Economy Works" by Goodwin.) "Debt" goes into the origins of debts, as compared to obligations; and related topics, such as exchanges considered beneath economic notice ("Please pass me the salt"), debts too big or unique to be repaid, peaceful versus violent interactions, the endless minor obligations that form the network of social connections, and even the basis of whole societies.
The reason I'm posting about this book here... is that it's giving me some new perspectives from which to consider the whole cryonics subculture, and, for instance, why it remains just a subculture of a couple of thousand people or so. For example, a standard LessWrong thought experiment is "Is That Your True Rejection?"; and most of the objections people raise to cryonics seem to be off enough that, even if those objections were solved, those particular people still wouldn't sign up - that is, they feel some fundamental antipathy to the whole idea of cryonics, and unconsciously pick some rationalization that happens to sound reasonable to them to explain it.
I still have two-thirds of "Debt" to go... but, at the moment, I have a strong hunch that one extremely strong reason people feel an emotional revulsion to cryo is, simply, that even if they do wake up in the future, they will have been cut off from all their social connections. This may not sound like much - but the part of "Debt" I'm currently reading discusses how one of the more fundamental aspects of slavery is that becoming a slave involves being cut off from one's family and society; and another fundamental aspect is that being a slave is being without honor, and in many senses literally having died (eg, in some societies, when someone was taken as a slave, their will was read and their spouse considered a widow). On a certain emotional level, many people really do seem to think that being probably-permanently cut off from all their loved ones is a fate no better than simply dying outright.
What's even more interesting is that if this idea has any actual basis in reality... then it offers the possibility of coming up with approaches to counter it: promoting the idea that waking up from cryo will involve being enmeshed in a community rightaway. I'm not actually sure how this might be managed. The Venturists seem to be heading in the general direction of that idea - but don't quite seem to be capturing it; maybe its the annual fee, maybe it's the dearth of concrete plans about how to help cryonic revivees, maybe it's something more abstract.
One possible alternative approach might be to take the thought experiment - what if we could revive someone from cryo not next century, or next decade... but tomorrow. What could we do to help them integrate into modern life, instead of merely waking up in a hospital bed with the day's newspaper and being shown the door? Bedford was frozen in 1967; how hard would it be to either collect or assemble a set of yearbooks, describing what's happened since then, and storing a small library of such reference texts at both CI and Alcor? Perhaps the cryonics providers' boards of directors could offer their members a revival fund that could be donated to, specifically targeted to help future revivees to rejoin society? I'm not even scratching the surface of possibilities here, so even if these particular ideas turn out to be wrong, at least they suggest further possibilities.
So: If someone was revived from cryonics tomorrow, would you be willing to at least let them crash on your couch for a few weeks?
