Of course facebook is very good for social network but twitter is the best for business and sharing opinions. But facebook now regard as a time passing area. So, i don't agree with you.
Facebook is probably one of the best innovations in the last 10 years, for both, socialization and business. Can't believe it was founded only in 2004... it's amazing what they achieved in only 7 years. I'm curious how long will they stay - hi5 was very popular once too
Both are good in giving traffic to the website. However, Facebook is much better than Twitter in Advertising your product.
a few days later fb will be broken. I'll hope it. Coz peoples are very curious of it. Very much curiosity dosn't long much.
I advertise with Facebook but I do not like PPC. They send me about four visits for $5 dollars in two seconds, and then my ads will cease to display until the next day.
