Differences in style b/w my posts and guest blogger's

The most notable style difference was the theme of the guest blogger's post as compared to my previous posts. There were some common misspellings such as, the description of a fellow co-worker as a movie biff instead of buff. Aside from my previous post on Office Romance, my posts tend to be very formal or business minded. So I think the main difference was the style of writing, which was more casual.
The guest blogger's post brings up a good point. Something that never really occurred to me and that is that I don't really have a personal connection with many of my co-workers. Most of whom are twenty years older and have families to take care of. Perhaps that is something I should work on.
