it would appear that gmail now has atom support. as far as i'm concerned, this is a vast improvement over all those menubar and taskbar mail checkers that have been popping up everywhere. the feed returns the first line of any new mail as a new item and the item points to my inbox. it's short, sweet and to the point. me gusta mucho.
even though i use bloglines for the majority of my feed reading i have a handful of personal feeds [see: private wikis, etc.] that i use newsfire for. thanks to the atom feeds it's one less website that i have to check on a regular basis. take that hotmail/yahoo.
