Formatted Text: Despite the fact that there are no formatting buttons available for making posts to Google+, there are still some minor formatting options. These options include bold, italics, and strikethrough. They can be accessed by typing *text* for bold, _text_ for italics, and -text- for strikethrough. Obviously don't forget to replace the word "text" with whatever it is that you want to add formatting to.
Import Facebook Contacts: One of the biggest advantages of Facebook is that you already have an established social network there. The Facebook Friend Exporter Chrome extension is a great solution to this problem. This extension takes all of your friends on Facebook and copies the information that they share with you - including email addresses - to your Google Contacts. This will make importing to Google+ a cinch. Unfortunately as of this morning, Facebook has blocked this extension, but the developer has said he is working on a solution to the block. If this interest you, be sure to keep any eye out for this extension to start working again very soon.
