The author is giving credit. Literally the opposite of your interpretation.
> I had the same idea in my notes app dated a couple years ago.
On the other hand this seems as if you now want to claim to be the inventor of the idea?
A mixture of both. Some of those were copycats and some of those came before me, (the iPhone app, but I didn't know about it when I made the website). The point I was making was there's lots of clones happening when you go viral.
