I just recently found the most efficient way to go through all your fellow followers blogs the best without overloading your system.
Read this :
Just put all the blog urls you want to open in a folder in bookmarks. Just right click on that folder and select "Open All in Tab". It's faster and more flexible...you can drag, drop, duplicate, rename, etc.
Make groupings of Blogs from 5-10 or however many your comp can handle comfortably and begin commenting on your friends blogs.
Thanks for reading, i hope everyone's blogging experience gets smoother and more fun.
