Hi Nathan! Thanks for the great post. I hope you'll like it. Invitel also has a new English site at http://english.invitel.hu/ so you'll be able to read it. We know, Hungarian is a little funny for foreigners, but we like it. :-)
I don't think firefox should be afraid of IE8. I have made somes tests, comparing a complex AJAX app that works fine in IE7, Firefox3 and Safari. It worked better in Minefield (Firefox 3.1) and it was awful in IE8. Check my blog for details.
Hi Nathan! I am the product manager of Sense/Net Portal Engine TNG. I am more that happy to see your post, and many thanks for writing good things about us. :) TNg will be available for download in September. We are working on a 1st release, that is good enough for a public download. As of now, we are working on the portal of one of our big customers, so we do not have time for managing a public beta program. Keep checking back to our blog.
