>That's what my blog's curation team does

And why would you move your blog to Reddit without curation team? It seems that Reddit does technically the same as Tumblr, you just have to move your site there and ask you mod team follow.

That's very, very unlikely to happen. People start their own subreddits and want more people, but it's just as painful to grow the number of subscribers as everywhere else.
