What is the best way to get Twitter followers?

Let's all share the websites and techniques that we use to get free Twitter followers, Facebook likes, and Google +1s from.

Here are my top 3 websites that I use:

1) Tweers - Followers, Likes, +1s, Stumbles, YouTube Views
2) Twiends - Followers
3) TwitClub - Followers

To get better followers or more facebook like you will need to promote your product properly. For example you can promote it via good content. A small and meaning full article describing your site. Second you can ask your friend to share your wall post. You can also encourage users to like your post by some means of contest or offers.
