The Blogs now has SSL encryption for logging in and the Admin section of your blog. This will allow you to safely use your Blogs over unsecured Wifi connections. In addition, you or visitors can view your blog over SSL entirely as an option.
Only Logins and the Admin area are forced SSL. If you have any issues, please let me know.
