Is it legit? Or just paid piracy? Who is doing the subtitling of these shows that are being released in Japan? (or is it only specific shows that get same day subtitles?)
Just information I've heard in passing, but they're legitimately licensing the shows. I believe they absorbed some subbers from the fan subbing community, but I believe their subtitles are in-house.
As for worth it's worth it, from what I've seen they've steadily been improving the sight. Stream quality has gone up, selection has expanded beyond a few easy to grab popular shows. Subtitles are well done. I'd say it's worth your time to give them a look.
