This forum is for those of our Indian audience who are not yet comfortable with the main forums. The purpose of the forum is to allow new Indian members to get a feel for how the site works, be guided by others, and eventually graduate to the main programming and discussion forums.
I too see it occasionaly, although it is more frequent in other sites. Suppose I searched for buying any item online then other sites when visiting I will be shown the same items so I beleive they use to track than and show personalized ads. Smart way.
