I'm hoping to find a way to make it profitable somehow. There must be something that I can sell to these millions of people who visit my site every day.

And I simply like the technical challenges it provides. I like optimizing and scaling systems and designing database schemas. I'm learning tons of stuff this way. If an opportunity provides itself to apply this knowledge I'll have it ready.

Pixeldrain as it's running right now could probably do 20 PB / month. But I have systems in mind which could take it to 100 PB / month at little additional cost.
