Ask HN: How to reach out to hackers and CS students in India and Brazil?

One good way to start would be to add the url/details in this post as well. Next, as suggested in other comments Reddit is nice, then Quora is also big hangout for many of your target audience (at least in India). Would probably need more details on the product to suggest anything more specific. If you are willing to spend some money, make a fb page and get some fb ads with product details, beta tester incentives and target to specific universities/colleges/companies perhaps...

Post the link here as well. Some students from India/Brazil and other countries would be reading hackernews as well and can spread the word. As others have suggested, try posting in reddit groups as well.

Thanks! That sounds good, but what should I ask besides putting the site and pitch it?
