It is in fact Atom. No one cares though. Not on the reading end. (On the publishing end, you ought to pick Atom, because most versions of RSS have many inherent ambiguities. On the aggregator developer end, you are left holding Dave Winer’s bag whether you like it or not, so publishers are the only ones who get to and ought to care.)

I tend to just write “news feed” to avoid the whole format issue. Some people use “RSS feed” as a category name along the lines of “kleenex”. It doesn’t matter.
