To answer those questions:
School Counselor Blogs that I follow and recommend:
-SCOPE (School Counselor Online Professional Exchange) well this actually is a wiki that has a fantastic blog roll of school counselor blogs!
The easiest and simplest way for me to read blogs is to read them on my iPad on my Pulse reader app. I wrote a post about how it is one of my favorite apps!
Starting a blog:
There are various (free) blog sites that you can make your blog on. I use Blogger because it's through Google and I like the ease of using it (plus there's a blogger app so that I can blog on my iPad although I'm not really a fan of the small keyboard). Other popular blog sites are Word Press, Blog.com, thoughts.com & Edublog. You should choose the blog that is easiest for you to use and understand, what works for me may not always work for you.
Blogging is a fun, fantastic and not to mention easy way to share ideas, thoughts and just general FYI with others. I've gotten so many school counseling ideas from the various blogs that I read. Happy Blogging!
