Link posts have the effect of taking you off the site when you're done reading. I don't like that about them; it moves comments off lesswrong, and I want to incentivize comments here. They also currently have a bug that makes it not really possible to see the comments section on lesswrong at all, but independent of that, I don't like how linkposts lead off the site. What are your thoughts on replacing link posts with posts that have the original source's content, but link through to where they're from at the bottom of the post?
Right - this is explicitly the plan. (We have tools for allowing bloggers to automatically share posts from their RSS feed onto LessWrong, the tools just aren't very polished)
Link Posts are basically a holdover from before we had this functionality. Right now I think they're pretty confusing and it's probably better to actually remove the option of creating Link Posts until we either make them better or decide to leave them behind permanently.
