I did this a while back using cobe: dumped in gwern.net, all my IRC logs, LW comments etc. It seems that the key is to set the depth fairly high to get more meaningful language out, but then it works eerily well: with some curation, it really did sound like me! (As long as you were reading quickly and weren't trying to extract real meaning out of it. I wonder if a recurrent neural network could do even better?) You can see some at http://pastebin.com/tPGL300J - I particularly like

I did avoid the Internet, in the Japanese media industries. One doesn't expect the sequences of marcello, but surely there were real phenomenon going on? Well, either you have a thesis? take that and multiply by the likelihood of various events in a set of stubby barriers (baffles) sticking up from the old-school method of people self reporting how much they owe each other. The first line is solid: the rhythm of travel still in his hand as the very poor reverting to low-tech, low productivity craft production of goods the wealthy can manufacture efficiently. One way in which a missing item has to be punctually at a certain time period (typically thirty seconds) will be agricultural. Drones can be used only once for any such study, using rhesus monkeys, was ["Effects of caffeine on hippocampal neurogenesis and function', Han et al, 2004), very little progress has been made to alter the design of Mark.06 is a bit secluded, but is at least 1 was a complete waste of time'
A> that is wonderfully coherent
B> That's more like it

gwern> '<@gwern> kurzweil is a flake...' <-- it speaks the truth!

'Medication' here is 'kusuri.'"] In order to ensure the birth of Reitaisai SP, an additional staff of 94, “over” 1,500 active archers in South Korea alone do not indicate the underlying conditions that will extend lifespan because it is contrary to the general corruption they are also unceremoniously written out of the picture." The remaster boasts sharper, jitter-free visuals with intensified colors; the enhanced audio is palpable as soon as unusually smart people. The best covered seems to be dead.''
gwern> damn, Reitaisai SP is going to be awesome - over 1500 archers are coming from south korea?
B> From there alone!
gwern> 'their arrows will blot out the sun!'
gwern> 'good. then we will cosplay in the shade.'
A> SMARTAAAA
gwern> LOLIS! HOLLLDDDDD!!!!!!

gwern> 'the video is killing the ref, I'm getting 1993/1994 addresses for that one episode and then went through her budget with them, if I set 'div#content { line-height: 100%; }', I still see the white snakes' <-- CSS would be so much easier to program if we could just get rid of the damn white snakes in the browsers!

Again, such an experiment is just a rose falling apart. The spacing between the items, there is Pentuple N-back (PNB) which was successfully read and converted to CSV by mdb-tools. The entries look like this (as before), the alternative system, but he must have misplaced it for a lifetime by homosexual acts.' <-- I realize I sound like a homophobe here, but I swear, the markov chains are quoting me out of context!
C> pentuple n-back converted to CSV. how does that work exactly?
gwern> C: oh, you just treat the black spaces as the delimiter and parse as usual
D> "such an experiment is just a rose falling apart" :)

gwern> '= 00:35 <@gwern> second episode of EVANGELION: he keeps undermining himself! there must not be very practical without them. but even if, say, NERV base. (Faculty of Medicine, Topol remembers being in the company to fund a significant bandwidth burden. It had become apparent that the producers who count-the marginal ones-are not especially likely to dislike strongly, as explained above. Small variations in observed market prices are thus less likely to find a hafu character, and, my ultimate goal, use technology to alleviate global hunger, malnutrition, and improve the soil." "Can we order them on the index, and we would say: Well, one would reach the right answer :) it's not even goign to be no less high. Over 2012, the result is that the long run they would get the right to ride on me and choke me to meet his gaze. “Can’t do the study to try and reach out with their thumbs. That's very rare. Rather, it publishes a program to ready the other chapters required much more X-ray energy absorbed in the '90s in part because legionary soldiers who could usually read, write and swim underwater!' <-- that's why Rome conquered the known world: fucking underwater legions
