While there may be a specific photo application you like personally, or an odd social network that’s your favorite, keep it to yourself. Your goal is to get as many people to join and participate. In many cases, you’ll have to stay with the most popular tools that people are already using. Unless the new tool is really going to solve a problem that none of the others can, go with the Web 2.0 applications most users will already have accounts with, such as Facebook, Twitter, Jaiku, and Flickr.
