Don't know if others had suggested it before or not. I don't dig old posts etc...
1 add "like" and "dislike" options in each posts, so for boring ppl they also wanna express their mind, they can simply push the button like or dislike a post. This way could aviod the "exhibition" of how boring far ppl can go on here
2 add "good posts go the first" option( automobily by votes of like or dislike), or simply "admin's choice" to put the best answer to the topic to be shown on each boring posts ahead. Then at least for not boring ppl they could find a mind on this site. I bet there are lots of "diver"around the site. They just read no join. Good posts always encourage more guys to join the site imo.
3 Why don't have a signature part under my posts? limit the space for 1 line signature is cool enough. Why don't let us earn some points for each posts?(for fun), so we know who are the oldest on here who are newbies, etc..
