Found this link a few weeks ago:
http://www.cdt.org/speech/spam/030319spamreport.shtml
Particularly interesting were these paragraphs:
"All the plaintext e-mail addresses we placed on the public web received some spam. The number of messages received seems to be related to the popularity of the web site. GetNetWise.org is a well-known online safety site that is linked to by major portals like AOL and Yahoo!, and the addresses posted there received a lot of spam, while ConsumerPrivacyGuide.org is a relatively new site, and addresses posted there received much less spam."
"But none of the addresses that were obscured, whether in "human-readable" or "HTML-obscured" form, received a single piece of spam, leading us to conclude that e-mail address "harvesters" are not presently capable of collecting such addresses. While this may change as time passes and technology develops, for the time being it appears that obscuring an e-mail address is an effective means of avoiding spam."
I think we're ok for now.
