Adding Atom support to RSS-consuming applications should be a matter of hours, maybe a day or two of developer time. This whole thing may be annoying, but it is not catastrophic. – TomI think it took about 2-3 hours to code and test Magpie’s (admittedly incomplete) Atom support, plus at least another hour to blog about it. So call it 4 hours total. (from 11pm to 3am)
As for the rest of it, we can only hope.
On a side note, Atom is clearly a failure as Ken MacLeod still doesn’t have a feed I can subscribe to.
