A few weeks ago, I stumbled across this neat little nugget web application called MeeID which is kinda like an online business card (for lack of a better description). It's so simple to use, it's free, and it's design is really lovable.
This is an extremely brief review because the application is just so simple and straightforward — and the design is very clean and intuitive. There's just not much to it, but it does what it does very well. All you need to do is sign-up for a free account, add your avatar or a photo, and then add some links... You can also add "favorites" or search for people and even get a random MeeID from the 1284 people who currently have a MeeID. It's cool...
There are lots of things that you can do with MeeID if you let your imagination flow. If you need some ideas to get your imagination going, the application's author Bronson Taylor has put a list of some ideas of what you can do with MeeID together for you.
Here's my MeeID in case you want to see another example.
