Aaron Swartz has a long post up on reddit.com's move from Lisp to Python. It's an interesting post - especially so if you are looking for information on Python web frameworks - but the anecdotes about the reaction of the Lisp community sound very familiar to me as a Smalltalker. Sadly, lots of people in niche development communities have "conspiracy theory" reactions to this sort of thing.
The funny thing is, this gives me an excuse to make a point about reddit versus things like digg and blogniscient. The latter two services provide headlines and snippets in their feeds; reddit only provides a headline (title) and an url to follow - even on their web page. As someone who reads primarily in his aggregator, that makes reddit virtually useless to me. I do a lot of scanning, and - while I favor full content over partial content - partial content is better than just headlines.
