Yeah this is the question which comes immediately into my mind and the answer is Yes. I got into this site recently when was searching for some consumer forum and it is a very good informative site. Everything is good about the site.
But their are some concerns which I got while surfing this site. People come to this site for some good information, but I felt some of the members misusing this facility like.
One of the member as created some dummy ids to rate his reviews himself, its really bad to see such things happen. I think so their are many sensible members who know what to rate and when. Some of the gem members who are really writing good reviews are

Jilmil
jimmy
sam1
asyis
amrita
smartgirl
thesmartest
churchillo
hetu
l
hitenmehta

The new members should learn from these members who take so much effort in writing reviews, but their are people who write reviews and rate it themselves using the dummy ids.

Nothing else i have to say. great site. Sorry, I cant write good reviews but atleast I will try to be geniune.

Love
