It has been some eight month since I joined the Entrecard system. (Yes, I was deleted by mistake, once.)
My first take is : It is good for bloggers. Good in the sense that it brings the visitors. Whether they stay or fly away in 2 seconds, thats up to the blogger. For my case, my articles are pretty short (in general) and are just meant to throw stones to the silent pond. Just rambling. I am not a professional blogger and never have intended to be one. Just as a part of hobby. It has helped me to improve my writing habits and support some cause. However, I can be worried about my PR and be excited by my alexa.
Entrecard is good because it brings you new friends and there can be ways to discover new blogs in the spare time.

The System could simply have gone in snap or be picked up by some giants, but it is surviving! So survival may mean leap towards being the fittest.
