I've thought of ways of working around this. There are ways of actually defeating the truncation. One issue is that there isn't necessarily an obvious programmatic way of telling which feeds are truncated and which aren't.
For now, try out this feed proxy: http://andrewtrusty.appspot.com/readability/ , e.g. http://andrewtrusty.appspot.com/readability/feed?url=http%3A//feeds.feedburner.com/planetrationalist
Thanks - will try that!
After input from many of you guys and the NYC group, I am announcing planetrationalist.com
There's a lot of different directions this sort of idea could go in, but I figured that this could be a good-enough first effort.
Enjoy, and let me know what you think.
