If you are interested in personalizing your PD, an easy way to do that is to create an account on Google+ and start joining communities. Google+ has been around for awhile, but, of late it has become a really strong support system for educators. It isn't as focused on the family, social and fun stuff people post on Facebook, but more of a professional based setup. I decided recently that I was going to separate my Facebook for my professional life and focus on Google+ as my professional platform.
Here is what you need to do to use it for your own PD.
1. Create a google account. (Gmail account holders already have Google+, so just login.)
2. After you create your google account, you can go to the search bar and type plus.google.com and it will open your Google+ platform. Under the Home tab, you can find communities and people who meet your needs. Some communities let you join immediately, some ask you to request to join and they add you. You need to make sure you have a profile
I have learned a lot of great tips and techniques from people on Google+, but like twitter, it can be a little overwhelming. Find some people on Google+ who you follow on twitter and add them to circles. (Circles are the "groups" people belong to. For example, I have a circle called Hoosier Educators, another one called Library People, and one called Edtech People. Some people are in more than one. It is an organizational method.)
It seems to me that Google+ is less social and used more by the masses for things like personalized PD. It is a great way to see what is going on in other school districts around the US and elsewhere. It is truly a great way to start developing your own personalized PD.
