Unfortunately Google Reader no longer exists, but if you are interesting in learning more about quilting, fabrics, techniques, and meeting new people, there are several websites that do a very similar job of compiling all your blogs and also helping you find new ones. My favorite two are:
This is the website that I use to compile all the blogs I follow. You can search by subject, by blog, import friends, and easily follow/unfollow blogs. It makes it super simple to start compiling a whole list of great resources. Bloglovin also has iPhone/iPad/Android apps so that you can read your blogs on the go too. ;) Here is a link to my page and it shows the blogs I follow, mostly quilt-related, to get you started if you don't already have a good list.

Another good site to use is Feedly. This site work very similar to Bloglovin, has iPhone/iPad/Android apps as well, but has a different layout and a couple of different features. It's all personal preference so try both out and see which one works best for you.
I also use the site Flickr to join online groups. There are groups that do quilt-a-longs, swaps, bees, hand piecing, etc. Here is a list of a couple of my favorites:
1.Pillow Talk Swap
3.Hand Pieced Quilt Along
4.do. Good Stitches Bee
I am personally a fan of quilting bees, they are a great way to get to know a smaller group of people, and with a small block a month commitment you get a personal quilting community and a quilt out of the deal! If you are interested in learning more about or joining an online quilting bee, this flickr group is a great place to start.

Hopefully that gives you a quick rundown of how to become more involved in the online quilting community! Best of luck, it's addicting!
