Just in time for SES, MSN adCenter had briefing this morning addresses several bugs and fixes they have deployed or are about to on August 5th. This is definitely an interesting development in the paid arena, wherein the Search Engine is actually addressing the issues and giving answers or solutions to the problems, not just "yeah we know about it and we'll get to it eventually" type of poo-pooing.
Bruce Clay actually has a nice summation of the MSN adCenter community briefing. One note I really took away from the briefing is their support for firefox. I guess they really must be taking note to what the percentage is of Firefox users in their stats -- it's got to be an eye opener to make them actually publicly announce the Firefox 1.5 support.
