Too many requests for guest post: Is it a bad omen?

Hi folks,

We all love to have guest posts on our blog, don't we? Specially if it a tech-blog. My tech-blog has gained (it seems) lots of fame in recent time and I am flodded with gues-post requests.

The problem is, these poeple are, as they say, free-lance writer who want to provide me with articles and in return want 1-2 link back to some sites (theirs or their client's). In most of the case, almost all, these sites are well ranked and have good reputation.

Initially, I was excited about it. But now after so many offers (in really short span of time), I am forced to think whether or not accepting theses offers is good for my blog's reputation and quality.

Any other blogger there with similar experience? Should I or shouldn't I accpet these offers?
