Only a month after rival comment system JS-Kit launched Echo, a real-time comment system, Disqus is striking back with its biggest upgrade since the service launched. Along with a revamped comment system, Disqus 3.0 is also what CEO Daniel Ha calls a "conceptual reconstruction" for the service: Disqus will now be split into two separate but complimentary products, called Comments and Profiles , in recognition of the way two distinct sets of users have been using the commenting engine. For those who just got worried about losing the Disqus they know and love, fear not: the service isn't changing all that much. The Comments product has been revamped, but it's still the commenting engine that bloggers can embed using a few lines of Javascript (we've embedded the new comment system below this post if you'd like to try it out for yourself). The new product here is Profiles, which Ha says is designed to cater not to blog administrators, but to empower the people who are actually out there leaving comments.
