I just discovered OwnCloud and ThinkUp. They both look like neat solutions to many problems I had. Going to tinker around with them and will let you know what I think of them sooner or later

Owncloud - use it to create your own cloud to backup files, sync a calender or create your own shortlinks for using them in twitter status.net instead of bit.ly.

ThinkUp - Analyze your twitter, faceboogle status, updates, new friends and loads of other statistics from your own server.
