I have been blogging here since 1996, but I always avoided blogging about technical subjects. I felt that my technical expertise (I am an email administrator and collaborative computing specialist) was the property of my employer and since I didn't want to mention them in my personal blog it was best to just avoid the entire subject.
Since I am one of the many people they laid off in the past year (including people with 25 years and plus experience) I no longer have an employer to worry about. Therefore I started a blog called Beyond Messaging. In actuality I started the blog to help my jobsearch. I have my resume (Domino and Exchange Administrator) posted, and have written some great posts about cloud computing, email, system administration tools, mobile devices for enterprise, as well as new features in Exchange 2011 and Lotus Notes/Domino 8.5.
So if you are interested in email architecture and collaborative computing give Beyond Messaging a look.
