Like to give out my simple flavors.me url as a first impression of my online stuff, twitter, facebook, flickr.

I love their connection to flickr which lets me make small photographer's business cards easily.

I love it's integration in Gravity (mobile twitter client) -> post short-url to instapaper when mobile, look up later at home on a real PC. :)

I use this for almost all my basic online social stuff - twitter, facebook and foursquare.

Nice pixel art on this classic sneaker.
