Guys, do yourself a favor and don't post these comments. You're not sharing any profound insights, you're just compensating for some insecurity you have.
In OP's case, I don't especially think he cares whether you thought his idea was the next Google. I base this on the fact that: A.) The site is already mature and B.) title says "my side project for over a year" -- so like, 1 year later, your negative comment is going to change his mind? Yeah, I doubt it.
If you put a year of effort into a nice webapp like OPs, you will have users, and people will enjoy your service. Also, this site is very impressive, and makes a good portfolio piece for sure.
I don't know if anyone is maybe getting the wrong idea. Personally, I don't click Show HN and then pretend to be PG interviewing the guy for a seed round. I click Show HN's to see cool stuff.
If you like it, then try it, use it, whatever. But if you don't have anything constructive to say, then you're wasting everyone's time, including your own.
