Almost everyone here into electronics (or able to use internet) can read English.Can't give exact figures but its one of the most widely used languages here.
Some friends of mine actually created a new account so they could comment. I really don't think I'll opt for a negative publicity by trying to make fake accounts and _then_ promote my business.
If you do suspect I have been doing it go take a look at the IP addresses if you like. I don't know how else to prove it.
In fact I do have two accounts on HN (n9986 and 9circuits), I didn't even use that to up vote. This post was honestly viral as it got re tweeted by friends and their friends.
My aim to get some positive feedback ended up with this.
Anyhow, doesn't matter now that this has been down voted to oblivion.
