India is a HUGE (and very beautiful country), Your potential audience is over a Billion!
One of my sites (which has over 20,000 members) and on it's busiest day/time (Sunday eveing) used to get up to 100 members online... Ad revenues were good and 200 new members signed up every month, it had been online about 12 years and I saw as it a growing success. The site is for a UK-wide charity and aimed at mostly under 25s so it has a limited audience.
However, after years of using rapidly outdating 10-year old modded-to-death version of InvisionBoard v1.0.1. We were always customising, and damn hard coding-in new features that I can confidenltly say far beyond what most social networking software currently offers. We not only had blogs but "group blogs", we had a "site news" like the newsfeed but it showed every activity on the site, even when we had people leave, or we recruited new modertors for which I created an automated Election/Voting system using proportional voting. The global mods could recruit new forum mods, so the online community was self-sustaining.
We had events pages with reviews when it had passed, RSVPs, a custom "Karma" system which had a points algorthym and checkboxes for "Interesting", "Funny", "Informative" etc so they could gain Karma for different things, and we wrote a Mobile Accessible site. All this years before Facebook or Twitter were even born!... it became cluttered, slow, lots of features were needing a complete change. Members - especially new ones often complained it was to hard to use and navigate.
Sadly it became unstable (especially when PHP5 came along!). I was writing a whole new site based on the old code (some of it we can still use) but have to embed it into Oxwall using iFrames etc, unless I can get my head around the Oxwall API and Plugin Framework (!?one day maybe!?).
We'd tried Drupal, Zoomla, InvisionCMS and Dolphin, they couldn't give us the hope and the tools to develop a new Social Netowkring site on the scale of our old one... then I started playing with Oxwall and realised "this is the one", it's open source, it's young and it's got a RoadMap to greatness and I am VERY pleased I found it!
