When those college tuition bills come in, be prepared for sticker shock.

Longtime readers of this column may be shocked to read the next few paragraphs, but I may have gone to the dark side, so to speak, or at least taken the first few steps in that direction. I recently landed a new contract for my computer business and was more than a bit distressed to find the office full of iMac computers.

Blogging is no longer just for the online-savvy. It’s for anyone who wants to share a little bit of themselves with the world. When our son was born, my husband started a blog chronicling every little coo and giggle so our friends and family could share in the experience as he grew. The site still draws readers several years later. One of my friends, a fantastic cook, created a blog to share her inventive recipes. I’m far more inclined to try something off her site than out of a cookbook.
