I attended a big conference this week and met a lot of new people. Very few of them carried business cards so we ended up exchanging emails. I typically closed the conversation with something like "Hey, it was great chatting with you, would you mind exchanging emails?". And then I would launch my Gmail, ask for their email address, enter some dummy subject and send it. Having an app with some quick intro where all I need to do is enter an email address would be much more handy. Any plans for making an Android version?
