As @lqlarry mentioned in his answer to this question, it might help the blog gain traction if it were more visible.
Is it possible to put a permanent link to the blog on the main site? Instead of replacing a link only when new content is available, could we leave the link there all the time?
It might also be nice if when new content was available, we could display the banner (similar to when a chat event is coming up) so users could know there's new stuff to read.
UPDATE:
Maybe the Community Bulletin board will help.
