How can I get reviewed on TC/Gigaom/etc ?
pedalpete: After a few months of writing to TechCrunch personally, as well as sending them my press release I finally managed to get www.HearWhere.com covered by them this week.This happened after TechRadar (http://www.techradar.com/news/internet/web/20-websites-you-n...) covered HearWhere. I don't know if having another site cover my site first had an effect, and TechCrunch never contacted me directly, they just wrote, and I found out about it after i saw a traffic spike.I don't know if it is the current economic climate, but TechCrunch did not drive near the amount of traffic I was expecting. Good reviews and comments, but as far as traffic, I saw an increase of course, but it wasn't a great spike in traffic I expected.With respect to your comment about 'no good .com domain names left', I have to call that a load of b.s.
If I managed to get "HearWhere" as a domain name, as well as some of other good names for other businesses, you can find a good name. 
It takes time, and can be a pain in the ass (it took me about a week to find HearWhere and maybe it was the 30th domain name I tried, but take the time and find a '.com' name. At the least a '.net', but '.biz' just doesn't cut it.
Plus, when freeringer takes off, you would be increasing the value of a .com or .net name, and making it a prime target for a competitor to get at your market.Much safer to get a new name I think.Your reasons for DOB and other data doesn't quite cut le moutard either in my opinion. 
Particularly if you aren't getting users because you are asking for too much information, then you aren't going to get the add revenue either.
