Show HN: List of 3k tech conferences, 358 open call for papers, 10k talks

Really great site! I found all (except one) conferences I&#x27;m interested in, even the small ones.<p>Where do you get your data? Is it manually curated?<p>And what&#x27;s the stack?<p>One suggestion: let me exclude tags in the filter.

This is really slick!
