I recently listened to this TWIT episode, and learned about ThinkUp.  It’s a project that Gina Trapani is involved with.  It lets you archive tweets, graph followings, see a conversation view of tweets, and a lot cooler stuff.  Check it out at http://thinkupapp.com/.

Here’s a nice fun screenshot:

Now if you have a wordpress blog and you want to incorporate Gravatars into your template, I suggest you use this line of code in your comment template.

<?php
  echo get_avatar( $id_or_email, $size = '96', $default = '<path_to_url>' );
?>

Replace $id_or_email with $comment (this is what I used) or with get_the_author_id() (it varies from theme to theme), replace XX with the size you want the images (I use 50 pixels), and replace ‘ <path_to_url>’ with the absolute location of a custom default avatar (in the case that the commenter didn’t have a gravatar set).  If you want to use the default avatar set in the WordPress settings (Settings->Discussion) you need to remove the default argument completely.

Hope this was educational, and remember to sign up for a Gravatar!

So with a little SQL and dissecting of this diagram, I figured out how to keep the content I wanted and delete the rest (without going through the web admin). All you really need to do is delete all posts except for those that are pages, then delete all comments (i kept 1), then delete all taxonomy terms by deleting everything (except for maybe the blogroll term) from wp_terms, wp_term_taxonomy, and wp_term_relationships.

It takes a little work, but it’s worth it.
