Karma isn't something I care about (unlike some). What I care about is how obtuse the tool was. I really wish I could remember what I was trying to add, but it took 3-4 times as long to edit here as opposed to the wiki. And linking other pages was a major pain.
I haven't tried since then, it wasn't worth the time and effort I put in. If that's changed, I don't mind spending days/weeks/months updating.
