But..getting into the beta was a giant PITA.
1. Enter email
2. Check email
3. Download client
4. Go back to email, copy code
5. Paste code
6. Go back to email, click sign in link
7. Browser asks if it's ok to open Yack
8. Create profile in Yack (at this point I bounced)
Honestly, just let me download the beta directly, open it and have it Just Work. This is a new product and people will be skeptical. Friction is therefore your enemy.
Would it be possible to skip profile creation as well?
