Brizzly is Twitter and Facebook's adopted baby
Today, Brizzly.com was made available for the public to use. You're asking yourself right now: "And why do I care?" Well, you'll care because it seamlessly merges Facebook and Twitter into one convenient stop. Why open two tabs, when you can just have one? That's the basic logic behind this mash up, and it does a decent job at presenting both well.
Its UI is a bit plain looking, and I'm not sure if I'm converted just yet, but it's a time saver... of sorts.
