I fell into this trap once with Skitch. It was a great tool, later bought by Evernote and totally ruined. Prompts nagging to sign up, redesigned UI, centered around uploading to evernote — the tool was ruined. What I need is a tool that lets me quickly snap a screenshot of a part of my screen and drag the resulting PNG somewhere, possibly annotating it with a couple of rectangles and arrows in the process. I've been using Annotate for that purpose for the last several years and it works fine. I learned my lesson and I am not about to use another tool designed to drive signups.
