One of the most important things about professional blogging is to have working rss feed. But most of the time even though people know its up there in the toolbar somewhere they wont click on it.

It has been proven over time that when you provide a Rss graphic that people will join your feed if they like what they say, but if there is no graphic they wont subscribe because most people browsing has a attention spam of 5 seconds. So even if the content is interesting they wont subscribe because of laziness.

A funny thing that people do is, that when you tell them to do something they generally just do it. Like when you tell people click here or there, they usually do it. Why exactly I dont know, I am not a psychologist but it  does really work.
