I have been raving about twitter for as long as I can remember but using it has exposed my site even more in my opinion. Implementing it not only will help you make friends but also make more money for you.
Do you know that twitter has a thing where your profile on there can help you earn money by posting up ads on your twitter profile?
You can follow me on twitter to see what's going on. I love this stuff because you get to post up what you are working on as well as get to know others on a personal level. I will admit that not everyone on there will get personal to take the time to chat with you on there but there are some that will.
If you want, can follow me. I will follow you back.
