How a guy was promoting a web site

I got a friendly email from a guy (I don’t know him) who was trying to promote his web site. It looked pretty new and was about sharing the developer resources.
He asked me to contribute. There are plenty of similar sites.
Next day I saw the guys is willing to chat with me in Gmail.
I wanted to know where he found me from and then see if i can help him. Yes I am often concerned where they get the email from. In fact I had number of similar situation and everybody was happy at the end of the day (they got their promotions in one or the other way, I just got “thanks” or something more material).

Here’s our short discussion. How do you like it?
At the end of it I felt like I owe him something. Ridiculous. Don’t you think so?
The part I like is that guys is talking how he liked my articles nut was not able to clarify that. Should I tell here what website it was about?
