Facebook and Social Startups Meme.

After staying in closed beta for a month, StumbleUpon’s very own URL shortener, Su.pr is now out of its Beta phase. The toolbar lets you shorten URL and share your favorite link across social networking sites like Facebook, Twitter and StumbleUpon itself. The site provides tools like scheduling that lets you decide when a message is sent to the selected networks. I need not say more on this save that it adds to the already swarm of URL shortening services out there, what will be more interesting is how it helps generate more traffic with its tools.
