org.com - I would not want it that badly, it is sort of backwords, but I could be wrong, it could have traffic just like .us.com names...
Yes, org.com and net.com gets a lot of traffic, millions of uniques/month.
cnet.com is loosing tens of millions uniques every month with not using wildcards. i.e. google.com.com OVT 1539, yahoo.com.com OVT 1684 etc., com.com gets about 0.02% of all type-ins traffic, which is huge. I can imagine however immediate lawsuits if i.e. they would develop on google.com.com or on yahoo.com.com some searchengine and directory. Wildcards are tricky...
