Once you follow people and get people to follow you back, one good way is to ask your followers for their opinions, ask open ended questions, easy to answer questions like what they're eating, etc...
You can follow people from this list: https://docs.google.com/open?id=0B9diy1D...c0ZtdUdDZw and within a few days they'll follow you back.

I like to engage with people who are watching the same TV shows as I am, so I'll search for the hashtags associated with the shows... .like #RHOC or #DanceMoms

Use tags while Tweeting and blogging on either sites.Like:
#myproblems
#theawkwardmomentwhen

People searching for that tag will see your post and if they like, they might follow you.

To gain more twitter followers I suggest you to join communities that helps you get more followers and give you a chance to be exposed to a thousands of Twitter users. Joining social media exchange platform is one of the great ways I know, speaking of social media exchange I found http://keeko.com/ very helpful in boosting once followers.

http://keeko.com/ is indeed a great site. I tried visiting this site once and I find it very awesome. In fact most of my fans for my facebook page came here (I don't use twitter but soon maybe). Try it out.

Hi by far the fastest and easiest way to gain a very large following on twitter fast is to purchase a low cost marketing campaign from a professional marketing company like twiboost.com (recommended)
There are 100's of other sites offering all types of follower services - credit follow based sites like twiends.com which are free to use and you can also purchase followers here using seeds/credits.
Not too sure about tumblr thou - mite be worth a looking on ebay or google as this type of marketing service is pretty rare.
hope this helps
