I've had great success with my webhosting company Pair Networks and the sister domain registry Pair NIC. Each has a referral program that pays me a small dividend for any new customers who sign up. So, if you're looking for a new hosting provider or domain registrar, consider using Pair. I'll be glad to answer any questions people have about the service — so far I've had nothing but excellent service and the prices are quite good.
Through the generosity of a friend-of-a-friend, I finally got a Gmail account (cantoni AT gmail.com). So far I've been pretty impressed, especially with its ability to group mail messages by threads. I pointed a couple mailing lists I follow to my Gmail account just to generate some traffic. I was pleasantly surprised to see how well it combines replies together in a threaded fashion. It's a good combination of digest most with the benefit of seeing each message individually.
More exploring to come. I wish it had import/export features — import so you could play around with more “real” data and export so I don't get locked in.
