Asked to add a comment quickly on a blog such as this with the built-in WordPress commenting system, you can easily step up to the opportunity. You may optionally write your name, fill in your email address, and share a tidbit. You submit your comment and voila!
At no point during the commenting process are you asked to register and prove who you are. You are not required to log-in to your social networking site account to comment. You are not required to create a username and password on some other site to comment. Here, if you want to comment, you can do it right here and right now.
Tough luck if you try commenting on blog with a third-party comment system. Try commenting there and you’re in for a surprise.
I applaud Marian Schembari for sharing why commenting is best with Disqus, Zac Johnson for explaining why Intense Debate commenting is the best, Guy Kawasaki for showing why the Echo commenting system is for you (formerly called JS-Kit), and Danny Brown for opining why LiveFyre commenting is better than the rest.
I grant those four bloggers that the third-party commenting systems have merits such as cutting down spam and employing social characteristics; but at the end of the day, they are registration systems and you have already told me why you object to comment registration.
Requiring someone to be logged into a Twitter account, Facebook account, Google account, or some other account as a prerequisite to leaving a comment on your blog is no different than the New York Times requiring someone to log in with a username and password.
If that floats your boat, good for you. But commenting should be easy and with as few hurdles as possible, no?
