longful:

I just keep my blog active :) I’m usually posting a new post every 6 or so minutes. It may seem like a lot of posts, but I gain about 500 followers a day from it (I post 250 posts a day, so about 2 followers for every post). 

I use Queue+ to keep my blog active. All you have to do is select a bunch of posts and you’re done! It’ll post the posts for you at a fixed interval :)

Once you sign up, you can also get a free two week trial for Queue+ here.

Just be warned that their support is kinda sucky :/ You usually have to pester them every few days before they reply.
