dear webmasters, Banner Exchange network: still useful?

[slowmo]

I have been wondering about this. Is banner exchange still very popular? Would you sign up and give it a try with your sites?
As a webmaster what is your opinion about them? WHere does it rank in your list of possible traffic generating tools?

thanks for taking the time to share your insights.

Depends, if you want to get on that more visits from that site the banner exchange is the best, if you want just for google it's enough a exchange a hidden link
