    Project mention: Ask HN: What tangible benefits did you get from spending time on HN? | news.ycombinator.com | 2021-03-06

    I've been following HN for 10+ years, first as a lurker and then getting into the whole "build something people want" thing. Over the years, I've "launched" quite a few projects here. Some have failed, while others have succeeded far beyond my modest expectations. But in a pre Product Hunt era, launching on HN was the only way to get exposure to your product. Even today, for a number of highly technical projects, HN is the best place to get the word out.

    While HN crowd has a reputation of being too cynical at times (the most famous example being the original "Show HN Dropbox"), over time, pre-empting how the HN crowd will potentially react and what kind of criticism a project might attract has actually helped me improve the product before launch!

    > I mean one day you got traffic 100K on the website. Good. But just for one day.

    My latest project, Typesense, which is an open source instant search engine (https://github.com/typesense/typesense) literally found traction only after posting here on HN. Yes, it was a ~50K single day traffic, but it had a permanent impact on the baseline traffic. So nothing is as useless as it looks :)

    Apart from the value I've gotten out of all these Show HNs, there is an incredible amount of value in the comments on HN. In fact, I often just skip the main post and just skim through the comments. Also, unlike certain other forums, snarky/toxic comments are discourage and moderated.
