2 Domains Not 1 Use

I own 2 domains formulafocus.net and angelsofaero.com

Both failed sites and struggled to find time on them. I was wondering if you guys have any ideas i could possibly use them for.

I love building websites, just fed up of failing sites.
If the ideas are good enough ill get building straight away.

I'd first consider the "struggled to find time on them" part of your post. Any good idea would require more time moving forward than you previously found time to invest. Do you have the time to invest this time around?

Oh yeah, i got the time, it just i lost interest and did other things like mess about on an old warcraft account. But i got a netbook recently which i was going to use for things like this.
