The Threshold Of Solicitation

I seem to have recently reached a new level of notoriety with Cheff Salad. People randomly email telling me about some article I should share with all my readers. Of course, I don't respond to emails written by robots (sorry if that makes me racist), but I appreciate this spam in some amount. 

As far as I can tell, not everybody who owns a blog gets these emails. There is a certain threshold of readership before spammers start pinging you. In a sense, this is a badge of honor. It says you are big enough to be noticed. 

The theshold of solicitation has many levels, though. You can tell when you have reached a new level of popularity when you find a new level of advertisers approaching you.
