Text-Link-Ads Questions

I still haven’t signed up for them – should I?
Are they like adbrite?
Are they preferred for Myspace sites?
Do they show network ads?

I’ve done a quick search and checked out their site but I haven’t found the answers to this question. If anyone can help, I’d greatly appreciate it.
Also, who gives the best ads for Myspace sites?
