If you follow this blog, which I highly doubt, you will notice that we have implemented a commenting system, so it's easier to comment and start conversations. We also think that it's easier to log into and use than the "old" blogger commenting system.
We wanted to use lifefyre, becuase of the "real-time" comments, but it doesn't support blogger (for now). This really sucked, because we were hoping for a better commenting system than other blogs, and BTW, everyone is slowly switching to lifefyre.
So we had to use Disqus, which is also good but lacks the great feature of "real-time" comments like lifefyre.
Disqus is being used all over the web! which make it easier for people who already have an account
If you have a WordPress blog, and would like to test lifefyre, just click here where it would take you through a tutorial. If however you use blogger, which isn't yet supported, and would like to try disqus, click here
