Information about Jabber-servers in a convenient table

Today my friend shared an interesting link with me
On this site you can see if icq transport is currently available, choose irc, msn, yahoo, aim transport for yourself, see which server uptime and choose the most reliable one, and also find out how long the server is turned off, and there are still many useful goodies)
I understand this does not draw on the article, it is rather a useful link for beginners Jabber users. So I will be glad if this note helps someone in the transition to jabber :)
