Ya, .info is good. Name availability is lower due to cheap price. But the .89 is easy to make, agreed.
I think the .us will work out ok. Even when they flood the market, those will all be globals, at least in the first wave.
Regionals willl remain strong, I think they are a pretty solid bet, if you live in a country with decent traffic/payouts. US, Germany, UK, Australia. Canada gets lower traffic, but the ad payouts are still good.
The engines are going to have to sort, and they are testing bumping local priority with co.uk, put on par or above .com
If the expiriment is successful, then you will see the same thing in other areas. Only possible exception is .us, there may be a tendancy to think of .com as .us local, hard to know there. Still think .com is going to be treated as the prime global, but other extensions with longer regs +/or established time will get a boost. Google wants sites that will be around for a while, and its going to increasingly look at local search and get better at content analysis as time goes on.
Anyhow, haven't written .us off yet for the long term. Its definitely good over the short term. Might have to make some transfers to other registrars next year, will see what the renewal costs look like around the net. Course if they are good enough to cover, I don't see much reason in moving them. The ones that can't cover are a different story.
90% of my portfolio is com/us/info so I hear you on the price thing. May end up consolidating sites at some point as I drop them off, haven't decided yet. Still in the throw them against the wall and see what sticks phase of things.
