Yes!
Thank you for asking, so that we can yell from the rooftops: Yes! Men already are an important part of the BlogHer community!
Nearly 20 percent of the people who attended BlogHer Conference '05 were men. Our first conference volunteers in 2005 were men. You'll even find some men listed on the BlogHer Blog Lists(read our requirements here).
Since there's been a lot of disinformation on this topic, we would like to repeat in no-longer-dulcet tones:
Gentlemen, if you are interested in learning more about women who blog, please accept our invitation to the greater blogging community to attend BlogHer conferences.
Now, may we ask a favor? Please copy this question and answer, and send it to ten humans who blog. Thanks.
