Or he could just like talking to you and appreciates that you talk back and enjoy his company, bear in mind you were on the dating site too, so why would it make him desperate?
i'm sure he's not texting you constantly all day, just see how things go and relax, if you like him tell him so after you get a feel for how and what he's like :)

No, that doesn't mean that he's just desperate. It means that he really likes you. If he always initiates the conversations, that further proves that he really likes you. If you like him back, then you should just enjoy his company. Go with the flow and get to know him.
