I disagree.  
There are posts on here stating the ladies are plenty busy. They can be selective because they can.

The economy is fine. Have you been to a restaurant, bar,  event, festival or whatever lately! It's packed with people shucking out money like crazy. Prices are wayyy up and still they spend.

To the OP.  
Good question. It's possible this site is dying.  
I don't know either but there isn't much going on here.

I see a lot of ads for ladies that never have any reviews here or any other place for that matter.

Economy isn't that "down" like people think....

Reason why I think...

1. It is summer... people are busy doing other things.
2. Site might be dying.... or people who are out doing these activities are not on this site
3. People have been seeing the "busts" in Bloomington area and might not want to broadcast what is going on
4. The 007 review thing.... They pop up because one time the home listing was MSP and that is why they keep popping up as MN reviews but they happen in other states.  Happens all the time.
5. Traveling women are not coming to MSP like they used too so that might be why SOME are not showing reviews and why keep reviewing the same women over and over and over.  Variety is the spice of life.  No need to keep reviewing unless something changed on the service.  

Those are my thoughts.
