I have been on Arch for a while now.
So far, not bad. Not too good, either, but it is a fun distro.
I am thinking of using it as a base for my ever-vaporous personal small server distro.
You can see any progress I make by searching for my packages in AUR (search for submitter ralsina). AUR is really a nice thing to have for a hobbyist. You put your stuff there, people can find it, they can even try it, comment on it, vote on it... really a very nice community site for a very hobbyist distro.
