Ask HN: Side projects that are making money, but you'd not talk about them?
Hi,
When saying a project "you'd not talk about" and then talking about it - it's kind of taking the point out of it :-)
But I guess I understand what you mean.
I have created <a href="https://yabs.io" rel="nofollow">https://yabs.io</a> just for me and let other people use it for free for now. It is a copy of del.icio.us for saving bookmarks with tags and then searching them easily.
I have also created <a href="https://www.gematrix.org" rel="nofollow">https://www.gematrix.org</a> for calculating Gematria values of words and phrases.
