Yeah, recycling the sequences was my proposal :) My current approach to that is to make a bot that auto-posts the sequences at a standard pace to the discussion section, since there was some complaints that this may overwhelm the front page and also, I think anything that needs modifications to LW software is dead in the water.
The number of meetup announcements on the main blog has been increasing. Though it's reasonable to try to get meetups high visibility to increase the chance that people who are nearby see the announcement, the posts themselves are content-free.
How difficult would it be to, instead of promoting meetup announcements, tag them "meetup" and put a "meetups" section in the sidebar, similar to "recent comments" or "recent posts"?
