Some people here have demonstrated an interest in establishing a blogging community. The easiest way to do this is leave comments on each others' blogs and to give them motivation to leave comments on yours with SE friendly backlinks.
Unfortunately, by default Wordpress has comments set to "nofollow" (I'm posting this because I just recently learned this myself - sorry to those who've left comments in the past

). WP doesn't have an option in the admin to turn this off so to change that you'll have to edit your code.
Edit: hony suggested a better way using the plugin dofollow.
How to disable "nofollow" comments in WP:
1. Open the wp-includes/comment-function.php file.
2. Do a find for "nofollow" in notepad, or whatever code editor you use.
3. Edit the line
Code:
$return = "<a href='$url' rel='external nofollow'>$author</a>";
change it to
Code:
$return = "<a href='$url' rel='external'>$author</a>";
4. Update the file on your server.
5. Give and get comments.
If you're worried about comment spam I've heard numerous people mention they're more than satisfied with
Akismet. It's free and easy.
Pleasant blogging.
