Not to quibble with your assertion, but why do you find the soulstone button useless?
I ask because my addon, SnaFu, is dedicated to information regarding the soulstone (along with ultra-lightweight Servitude replacement), and it would be helpful to see another point of view on the usefulness of information tracking with regard to (what I see as) one of a warlock's key roles in a group.
If you solo all the time, I submit that this will not always be the case.
If it's because you use SnaFu, then that's awesome. :)
I'm neither developer nor author, and I love SVN :D
Before I start WoW, I just have to open RapidSVN and Upodate all my Addons. Done.
No more searching through overloaded websites, if there is an update.
SVN > all ;)
updating via SVN == lazy.
I will grant that typing "svn update *" and going then going out for dinner while you wait for it to finish is nice, but it slows down the SVN for everyone.
If you're concerned about "overloaded websites" (by which you probably mean Curse), use the "add to favorites" feature.
Hit up Curse/WoWI/ui.wow every evening and check your favourites page/profile and download the update yourself. Unzipping a bunch of files is not that hard to do.
How is the SVN any better than uploading it to WoWInterface for the people here?
As it stands now, SVN hosting benefits two classes of people: Authors and Developers.
For the masses, going to svn.wowace.com/files is just as easy (or difficult) as surfing wowinterface.com and tacking stuff up on their favourites list. Harder, actually, as scrolling through the /files/ list is a bit of a pain to figure out what's been updated recently.
