I gave up for a number of reasons...
MyBlog is moving towards two years without any sort of update. The CSS is not written that well even for the time is was released--and trashes out very easily when using newer templates--and almost guaranteed when using a Rocket Theme template that employs the Gantry framework. Lots of bugs--and the load order of the libraries and scripts (now outdated) can cause multiple errors, warnings, and issues depending on when it was installed in the site DEV cycle.
As everyone soon discovers, some hacks to core JomSocial files are necessary to try and get full integration with JS--ones which are erratic at best in whether they will function or simply cause errors that result in blank pages instead of your site! Review the forums at jomsocial.com for many details. Not a lot of support for it is found there--and what support exists on the azrul.com site has been abandoned or is neglected. With all this in hand and after a month of fooling with it my decision was to go with EasyBlog.
The developers there and here have gotten the integration working solidly--without the use of hacks or the need to change any core files. It is all done through plugins and interfaces. This way upgrades to either EB or jComments do not require re-hacking and the extreme likelihood that the new versions will no longer work with older hacks. If you have any sort of membership to a community that is something that you do not want to happen.
