2) Useful. I can capture my screen, draw on it, highlight issues or bugs or whatnot, and share it.
3) I know you'll keep it running because it has an obvious, lucrative business model (assuming you monitor what screens people capture for the occasional useful password, credit card numbers, stock tips, blackmailing opportunity, etc...)

As a precaution, I minimized everything. :)
I use a clipboard manager which is nice, and past copies are saved for a defined few hours or additional entries.
