The following are some of the pet projects which I am involved in.
RoloPress
RoloPress is a WordPress based, open source contact manager, which I am developing with my friend Steve Bruner. The main distinction of RoloPress is that it is an application build on top of WordPress and is not a separate application with is tied up with WordPress.

King Ping
King Ping is a web service that enables you to ping, (i.e.) to notify, 18 blog search engines that you have updated your blog/website. King Ping can be used with any web feeds (RSS or Atom). After you ping them, your new content will be indexed in their database on the spot, ready to be read by other readers. If you do not ping them, then your content will not be indexed or only indexed much later.
