"I am not very good at talking to people. How can I talk to them about SFI or TripleClicks in a simple and easy way?"
Good question...
There are several ways, the easiest and simplest is:
If you have the experience to make a blog, and the blog oglašavaš SFI and TripleClicks, therefore you create communication with people.
The other side is that you ask your links from SFI and TripleClicks the various forums, blogs and web sites for advertising with their own advertisements.
Thus you will gain mostly communicate with people, but my suggestion is that you make your own blog, and so achieve your effective communication.
