I think deep down Rob isn't looking for ways to improve AROS or the AROS project--he's looking for ways to improve the AROS community. It's plain from his blog that he enjoys the camaraderie and collaboration found in most Linux projects. Frankly, there just aren't enough interested developers in the Amiga community, AROS or otherwise, to make a difference in that regard.
When Amiga developers do come together in large groups, they're just as likely to kill each other as they are to help. It's a sad, sad, world we play in. There are exceptions, of course, but bad experiences amongst Amiga programmers are not uncommon.
