Twitterlicious is a mashup of Twitter, Del.icio.us, and Ma.gnolia.com.

It was first inspired before Twitter had a mobile interface. I built a mobile interface to Twitter to use on my Motorola Q. Then, when I saw Twitter had come out with a mobile interface, I knew that for it to be useful, it had to do something new.

That's when I mashed it up with Del.icio.us & Ma.gnolia.com. When you're viewing your or a friends' timeline, you have the option to "clip" the tweet.

Doing so saves the URL for that tweet in your Del.isio.us or Ma.gnolia.com account as a private link with a specific tag so you can come back and view it later. So many sites linked to in Twitter are useless on mobile devices, that this clipping is incredibly useful.
