@wot, I'm glad to hear your site is doing well.
I notice it ranks on the first page of Google.co.in (despite it being a parked domain).
wot, do you intend to put a site/mini-site on Ludhiana.net.in? I think it will increase your chances of staying in the index!
Nope, simply going to try to sell it along with the majority of my .co.in/.in - hopefully this year so look out for bargains.
Best of luck with the sales. I know you own a lot of good domains!
As you probably know, Google doesn't intentionally index/rank parked domains.
