It looks like Karen will be attending the BlogHer conference. From her post it seems she'll be part of a session with the following abstract

Women around the world are leveraging blogs to get their message across - whether it be to share their experiences, promoting their business or voicing their opinions. But changing the blogosphere doesn't just happen from blogging about it - change can also happen from the source - those who are building the tools and software. Technology isn't as male-oriented as you might think.

Did you know that many of the big-name blogging tools have women helping to design and build them? Ever wonder how decisions get made or why things are designed or work the way they do? We invite women interested in helping to shape blogging tools and those currently building blogging tools to participate in this forum. You don't have to be a techie - share your thoughts and gripes on blogging tools today.Tell us what you what to see happen.

To many people the most familiar female face when it comes to blogging tools is Mena Trott. However there are a bunch of women working on building popular blogging platforms such as MSN Spaces who have been quite influential as well. For example, when I joined MSN the Spaces team had women in key positions; Karen owned the blogging experience, Divya owned photos and Lydia owned profiles. Since then some folks have come and gone and although Divya & Lydia are no longer with us we've added Maya who works on cool top secret stuff and DeEtte who now owns the photo experience.

Although A-list and tech blogs tend to be filled with testosterone totting geeks pontificating about pointless geekery this doesn't mean that there haven't been women involved bringing one of the biggest revolutions in personal publishing to the world. 

Hopefully, the BlogHer conference will be a useful way for some of these women to network and find a way to increase the visibility of their efforts. If that is what they want.
