As people are becoming more interested in Comet, “which Comet implementation should I use?” is becoming a common question.

At Comet Daily, we recently had a post comparing the maturity of various Comet implementations. From this, we came up with the idea of a Comet Comparison Guide to make it easy to learn about the major differences between implementations. We still have to add information about the Comet servers not developed by the contributors to Comet Daily. Once finished, we hope to have the definitive source for quickly comparing the options available for implementing Comet.
