Twitter is a great box containing everything and anything.
To attract all of these things from the box into your own box of products and services, is called becoming interesting.
Being interesting on Twitter is a key way to get new Followers and eventually they will be your future clients, or a prospective buyers.
Knowing that being interesting will help your Twitter account, feeding your account is a great way to do it.
No, not giving it bird food, relaying a valid RSS/ATOM/XML feed through it.
Relaying news or blogs to attract people's attentions to your Tweets will get them to find out that you really are an interesting person.
Google Alerts is a great way to do it.
First, check out the latest things in technology or real life.
Let's take New Moon for example, set up a Google Alert that searches for New Moon in the News.
Create a feed out of it and relay each Feed item to your account.
When people notice that you are Tweeting things that are related to them or interests them, they will eventually Follow you.
Although, Tweeting the same topic over and over again will eventually overwhelm people.
Even though you are relaying feeds over your Twitter account with such interesting and relevant things, you have to be creative with the way you do things.
Maybe set up another feed related to New Moon, such as one of the actors or maybe a movie that is very similar, or maybe put some Tweets about what's happening at your company or business, but still relay your feeds at the same time.
Keeping things fresh and new will keep people on their toes, and will put you on their "always watch and follow" list.
Being interesting is a key concept of Twitter; to be interesting is to be related to something that has a liking in a certain person; if they like New Moon, and you tweet about New Moon, of course they are going to follow you.
Stay interesting, and your Follower count will always be rising.
