I roll with 88 addons. I haven't had to update any of them in the past two weeks, and that was just for SellFish. A few of the addons have had new versions uploaded, but the old versions I have still work, so I do not feel the need to update them. Should they stop working, I'll know where to find the updates because I have all of them favorited.
The exception to lack of updates is Pitbull 4, an alpha. If I come across a bug or problem, then I'll only be hindering development by posting a bug report based off an outdated version.
