There's a TOI report on this here, which additionally is an item on Microsoft's IPR scholarship awardees.
Just took a look at the portal itself. It has this to say on the home page by way of introduction:
LegalAdda seeks to build a vibrant community of legal professionals in India.It is an interesting concept, and slightly different from the existing legal portals on the market, which serve as agglomerations of laws and rules (and occasionally offer legal advice) more than anything else. The USP of this website appears to be that it is essentially a social networking site, and a space for people in the legal world to meet and connect with each other. I am curious to see if this will catch on.
The site aims to facilitate collboration amongst the legal ecosystem and network with each other. We invite students, practicing lawyers, law firms, colleges & universities to actively participate at the site.
At LegalAdda, you can participate in discussions at the forums. Your white papers on legal topics are invited at the "Contributions" section. Events of interest to the legal community can be shared at the Events section. "Jobs and Internships" tabs provides opportunity for prospective employers to post their open positions. Candidates looking for internships & jobs can benefit from this section.
As an aside, this claim from the Microsoft India chief paraphrased in the TOI report had me laughing for a bit:
Microsoft, which sings paeans on Indian talent, has refrained from developing a country-specific product mainly because of high levels of piracy and poor awareness among law enforcement agencies.
Same old, same old. Do we need to get into that debate about pricing it right again? Sigh.
