How do you get more followers on twitter and tumblr?

[Nicholas]

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
