I think prices for .com/.net should go up too. Too many domain squatters and advertising-only domains. If it was $50 a year, some good names might become available for real businesses.
Or just regular registration. I have near 100 that I registered with good intention. Then I get distracted and later I'll look at my list and be amazed at the quality of the names I have. Nothing that I could sell for much, but that would be great memorable names for a service or company. They're so cheap that it's no big deal (at least in bite size chunks), but the truth is I'm locking it up for an entrepreneur with the time and motivation.
