In case you didn't know, on 12/12 they first announced sneakily on the Russian journal of LJ's design guy that with new changes being implemented tomorrow, there will be no more subject lines in comments and that this change was "non-negotiable" (good round-up and translation here). I'm sure you all realize that this will basically make fandom and RP communities unusable. LJ's staff, however, doesn't give a shit. At least 18 pages of 100% negative feedback didn't sway them.
They've backpedaled some and will make keeping comment subject lines optional in some S2 styles, but the default (that 99% of communities are running right now) will decidedly be subject-less! Not to mention that their new and frankly, fucking ugly design will take forever to load and make the site a pain to use on mobile browsers.
And oh, it looks like they might be taking away the drop-down menu to select icons as well, so you'll have to load all your icons as pictures to select them. Lovely. (I will beta-test tonight to see if this is actually true.)
Really, I don't know why I'm surprised. LJ is always fucking with the parts of the site that actually work and breaking them, so this is just another instance of that. Because seriously, who are subject lines hurting by just being there? (And no, it can't be a matter of server strain, considering the new "graphic" interface will definitely be using up more resources - so much fun when there's DDoS attacks!)
As far as I know, they've never once listened to their customers, so those thousands of comments already posted probably won't do shit. I've left a message expressing my concerns about the new comment pages here anyway; so if you want to do that too, go for it! If anything, it helps with the rage. ;)
