Sometimes I really wish there was a site like MyAnimeList but about seiyuu.
Like you’d be able to list which seiyuu concerts you watched, write reviews, boast with amount of singles and DVDs owned, share scans and photos (with quality control) and whatnot. Would also have the ability to search anime based on the list of seiyuu provided so you can watch something having all the voice actors you want there (a feature really missing from MAL).
However I doubt MAL will allow anybody to borrow its design and I don’t feel like having a site with generic design instead of the one I’m used to and like.
You just get used to this urge to add a concert you’ve just watched to “completed” somewhere, otherwise it’s just not complete for you, you know?
