Sorry for digressing from the general discussion on UPSC preparation, but ever since the start of "Pattern Change" threads which resulted in influx of heavy traffic to this site, we can see some changes in the layout and placement of the advertisements on this site. This makes me wonder about the economics behind the business model of this site and similar sites like mrunal's.
p.s. :- it would be better if we could move beyond the politically-correct and modesty-dripping notion that these platforms are only run for the general welfare of aspirants and there is no commercial angle to it.
Fast and steady wins the race
