Which traffic would u prefer to receive for trades?
 

would u prefer to receive a tgp clicked blind text link to ur tgp/mgp

or

would u prefer to receive a text link that is niche specified.. the only problem with this is that the traffic would come from galleries on ur site (exclusively).

Hard to say...

A surfer already on a gallery is 50% of the time satisfied, and doesn't want to see any more.
The other 50% on the other hand is dying for more and will click more on your main site.

On the other hand. The surfer that came from a blind link was expecting to go nuts on the "chinese chick with big DD-cup boobs" but ended up on your site. The best thing to do as a surfer that is dying to blow his load is to click on your site too.

It's a two way street if you ask me :2 cents:

It seems to me that niche specific traffic would be much more productive and would therefore be much preferred.
