They probably are of interest, but let's not forget he's running a company in his spare time, and 3 releases in about 3 weeks is a pretty good work rate.
Of course, as someone running Arc in Windows, I'd love it if a bit more stuff worked out of the box (e.g. the blog, which didn't work in Arc1 IIRC). That's why I'm probably going to switch to developing on Anarki and then testing it on vanilla Arc afterwards.
Note that I don't criticize Paul's attitude there. 3 releases in less than a month is much more than what I expected. He didn't release early, but at least he releases often :) I just meant a few things would deserve a little more consideration, at least in the next few weeks/months ?
