Mashable summarized a report from Hindustan Times that Rediff's addition of social media functionality has dramatically improved the Indian portal site's stock valuation.

This from Hindustan Times:

Rediff's stock has witnessed a sharp jump in share price and volume on Nasdaq over the past week, when it also launched a Website to help consumers upload voice, video and photographic content for free.

In 8 days Rediff's share price spiked up 40%, from $17.94 (on July 5) to $25.41 (on July 13). HT goes on to report a possible sale to Google or Yahoo for over $1 billion (US).

I'm looking forward to the day when adding social media functionality is as commonplace as including forms on a your website. Then we'll really get back to our roots.
