Blogger introduce RSS feeds

I just learned that Blogspot introduced RSS feed, just very recently. It seems odd seeing they already have ATOM feeds, why all of a sudden introducing RSS? Besides, RSS version are older than Atom, its going to be obsolete sooner than Atom. So why are they releasing RSS then?

Also, it appears that RSS list the last 25 updated items, which is different from their Atom feature because unlike their RSS, they only list the selected number of post you on the front page. Weird, why the disimiliarity.

Lucky for us, Blogdrive have long been supporting both RSS and ATOM. And Blogdrive displays a reasonable number of items (10).

However I do hope that Blogdrive will introduce some RSS features such as editing options (HTML) or whether we can publish full or partial feed... I've included this in the forum topic asking for more features.
