If you want an automatic updater, you can get Cosmos, or talk with someone here to get one built-- it wouldn't be too horrible.
When svn.wowace.com/files first went up, I took a couple hours and wrote a script to automagically update & install my addons using that. It's not only easier, but faster than updating with subversion was. I really fail to see the problem with losing subversion access. :)
Care to share it? While a chunk of us probably have no issue creating our own script, I'm guessing a larger chunk do. It could almost be a mod in it's own right - a simple script ala curse-gaming where you mark your 'favorites' and it indicates if there is a new zip available.
If nothing else, it would let this thread die and people could link to the script in their signature to taunt the newbies.
