I would use this, if the same company hadn't bought skitch and then completely failed at keeping it working. RIP skitch.
The old Skitch UI was ugly and non-standard but very functional. I like the direction they're going with the new version of Skitch, but they should have waited to release it until the features were comparable.
Forcing Skitch to sync with Evernote is also awful. Every time you quit Skitch now, it nags you about needing to sync. I understand why they need to do this, but the UX is just bad.
It's reasonable to decide to not use free software because you need more support than the vendor can provide.
It's unreasonable to be upset about a free software vendor not providing enough support.
This is like the whole can't-get-a-human-at-Google-when-gmail-breaks issue. If you don't like it, pay $50 a year and you can call someone. Or stop using gmail.
