A couple of days ago I was approved as a contributor to Product Hunt, so I decided to post A Hacker's Day there. I did not think it would be as popular as it got but it ended up on the frontpage and received over 120 upvotes. The traffic to my site increased and I was really happy.
Throughout the day I received many exciting emails and many people wanted to be interviewed and fetured on A Hacker's Day.
The only marketing I did around this was to post a thread on the IndieHackers forum, but by then AHD had already received a lot of upvotes. Thank you every one for all the upvotes, it means a lot!
