So, I've been wanting to create my own URL shortener for a while now but have been struggling to come up with a short enough domain name that was also meaningful. Today I discovered that cwf.me was available and decided to use it as my short url.
I was going to write the application myself but then uncovered an open source system which does exactly what I wanted to do and then some, Yourls. It only took me about an hour to setup and love how it turned out.
If you're constantly posting links on Twitter and Facebook, I highly recommend getting your own URL shortener just because it builds your brand that much more!
