Yep, big fan of Entrecard here!
The truth is, it's like anything else in blogging, business, life.....whatever. Your results are in direct proportion to the amount of effort that you put in to it.
Maybe it didn't work fast enough for you, so you were down the road. I find that the case with many things that people are not happy with. Did they really give a 100%
I have made several posts about this here and at Entrecard.
Entrecard is a great tool for people looking to generate traffic. I have gotten a bunch of quality readers and loyal commentors.
Entrecard has increased my Alexa rank from 500,000's to a current 208,000 in about 2 months. My weekly average has been between 55,000-80,000
Heck, that's just my experience! This is working well for several blogs that I own that are managed by others. I am going to keep on keepin on Entrecard!
BTW - I'm not saying that the lack of effort is any of you.....it's just merely a general observation and rhetorical question really. Only you know if this is you.
