Hello again!

I can generate ideas from nothing! By the way, talking about nothing: It would be great to have a (shareware?) program which do nothing. The trick is right here. Your program (site) might have a label on the main screen:

I'm doing nothing, so feel free to turn off the monitor, take a day off, relax, visit your parents or your favorite place and be sure: I won't do anything!

This will work as psychological air.

And how can you get ROI > 1? It's easy - people will be thankful for the free moments, your program presents for them. Ha-ha, you can do even better: while this program is trial it does nothing,but after 30 days of usage it could start doing something :) (format drive, please!).
