One thing I noticed while using Livefyre is that you still need a way to block or moderate Trackbacks coming to your WordPress site, this requires that you still use Simple Trackback Validation with Topsy Blocker to help prevent trackback spam from showing up on your WordPress blog with Livefyre.
However, I was able to remove GASP, Ajax Edit Comments, Akismet, ReplyMe, Subscribe to Comments by using Livefyre so using the Livefyre comment system allows me to remove 5 other WordPress plugins which reduces load on my blog and helps keep it trim. As Livefyre requires a user to return to your blog post to reply to a comment it was redundant to have ReplyMe installed and sending out a 2nd email to a user to return to the blog and comment since Livefyre automatically sends email when comment is replied to (unless user changes their Livefyre account to disable notifications).
Overall I am pleased with the amount of SPAM livefyre has blocked since being installed on my WordPress blogs, though I have seen a drop in reader comments most of those comments were spam comments making it through my approval queue. I found the majority of my regular readers and even the readers who comment for SEO linkbacks are still commenting on my sites even with Livefyre installed.
The livefyre system still however needs quite a few features that it is lacking and it isn’t designed around multi-author blogs very well. More in another post about this on DragonBlogger.com later.
