When I read a good post, I like to inform the writer that I liked it. LIKE buttons allow me to do this with little effort.
Sometimes I like to comment on the post, so I do. But I’ll tell you, some blogs make me jump through hoops to get that comment added. A few make me do it twice. There’s one blog I never comment on anymore because I have no idea how to get it right the first time. It is frustrating to write a comment only to have it disappear without a trace while I am answering math questions or figuring out those wavy letters to let the host know I am not a robot.
