Last Wednesday I added an update here that I'd posted AnonAddy to Hacker News.
The post has now been up for just over a week and currently has a total of 393 upvotes and 174 comments.
When I first posted AnonAddy to Hacker News nothing happened for half an hour or so, it received 1 upvote in that time I think. Due to the number of submissions to the site it had also now already fallen off the first newest posts page.
I thought that would be the end of it, buried and lost. Luckily I had posted it to Show HN: and it was still on the show newest page. All of a sudden it started receiving upvotes, it quickly went up to 10 or so and shot to the top of the Show page.
It then got onto the front page of Hacker News and stayed there for a day or so reaching a highest ranking of 4th!
I could barely keep up with the comments and for next day or so I was solidly replying on Hacker News or to peoples' emails.
It stayed on the first page of Show Hacker News for about 3-4 days!
The feedback has been absolutely great and almost entirely positive!
I'd definitely say this launch was much more successful than my launch on Product Hunt. Perhaps because I did it midweek instead of on the weekend or maybe because the audience at Hacker News is a better match for the site.
