It's actually trivially easy to make text stand out on any background -- let me, as the user, change the font/size/color in order to make it readable.
In any case, though, this is clearly moot. 2.5 years later, Skitch 2.0 is still a joke. In fact, if there's still anyone at Evernote who reads the forums, please note that the job you did on ruining Skitch is one of the major reasons that I no longer use Evernote.
