Strikethrough, nipplegate, general bending over for commerical interests or interests that CLAIM to be commercial or powerful to the detriment of user experience, rolling out new changes including adding ads to previously non-ad accounts with no prior notice and no request for feedback, utter lack of transparency, and even holding an "election" for a "user representative" with no specs whatsoever for what the role entails and apparently no intention to have the role be anything other than smething intended to distract the user community from their latest fuck-up. Failure to ever come down of the side of free speech, even with Lessig on the advisory board (not that they ever listen to the advisory board), turning a blind eye to spammers and heavily encouraging commercial interests. Ordering its volunteer staff to do arbitrary things with no explanation, and forbidding them from offering any explanation to users.
Contrast this with DW: ALREADY transparent, committed to open source and interop, deeply involved with its user community, committed to a no ads stance, even set up the company to make sure they could be politically involved in matters like free speech. Some have said it's like LJ in the old days, except LJ in the old days kinda happened by accident and Brad was clearly never committed to the long haul - or even thinking about it - in the way the DW people are.
On the downside, as I mentioned, most of DW's userbase so far seems to be from the vocal whiny fandom crowd of LJ, which I guess is better than the trolls, but in a certain sense I'm kinda holding out to see if some more, well, sane people migrate over before I get too comfortable with it. Them being the first ones to go DOES make sense, tho, since they were definitely the most abused by 6A/SUP over the past years, and I wouldn't be surprised if SUP's official stance on their mass migration was "good riddance".
