compared to other pokemon forums serebii is still going pretty strong, though I have moved over to PokeCommunity last month, haha. PC is laggy as hell but the discussions seem more interesting and fun. PC has a lot more features as well.
NO DON'T WATCH ALDNOAH.ZERO, I hated it. I may love mecha anime, but that was complete crap. Don't bother, lmao.
recommendations:
1) Haikyuu - sports anime, but you don't have to like sports to enjoy this (if you do dislike sports, that is), because everything else is so good
2) Angel Beats! - pretty classic anime with good story, good characters, and great humor
3) Baccano! - one of the most mind-boggling shows I've seen, storytelling-wise. it's pretty heavy, so you may want to save it for later, but the plot is incredible. every character is related to another in some way, and the story untangles itself nicely
4) Durarara! - same reason as above
5) Fate/Zero - the fight scenes are godly
6) Gekkan Shoujo Nozaki-kun - sounds cheesy, I know, but this is the most hilarious anime I've watched in a LONG time. lighthearted show to pick up easily.
7) Fullmetal Alchemist Brotherhood - I doubt I have to explain why; everyone is going to tell you to watch this show at one point or another
8) Hunter x Hunter - very long (in the 100 eps range), but worth it. I'm actually going through it right now, and I'm very impressed by how the arcs have been set up
9) SKET Dance - the longest comedy show I've seen. the episodes are very amusing, though it's 70eps iirc, which can be a struggle to get through
so that's what I have off the top of my head! also, note: 3, 4, and 5 are the most violent and are pretty gory. if you're wary of that, you should probably steer clear away from those. I'll rec you some more lighthearted things, if that's the case
