I'm thinking of web app for sharing lists of installed / recommended apps with people. Optional comment for each app on how/when/why it's useful. Something a bit similar to usesthis.com, but for sharing Android apps and open to everyone. Is there such a service?
Generically, a user's app list will be at
You can also create other lists to share with the world.
Although it's not a webapp ShareMyApps is quite useful. It is tiny in size and can share application list via email where you can edit your application list freely.
