I had heard so much about ASO so I gave it a shot and I love it. I have had great support from them on technical questions. I have experienced no downtime yet and have had zero problems. It's been over a month now with them and so far so good.
Glad to hear things are going well for you. I agree with your take on Yahoo!, as I used their GeoCities (free and then paid) service several years ago, and found it severely lacking!
Anyway, please check back in after a couple of months and let us know how things are going then with ASO! Cheers!

siteuptime.com offers free 24/7 monitoring if you want to know for certain, though I have seen this produce some inacuracies from time to time. I have had nothing but good experience from ASO in the past personally so I agree with you 100%.
