With 30,000+ ( yes, over thirty thousand now! ) downloads so far, Comments Evolved for WordPress ( formerly Google+ Comments for WordPress ) has been a huge success. I've just released version 1.5 and if your not yet aware of the plugin, It makes the comment section tabbed adding tabs for G+ Comments, Facebook, Disqus, WordPress Comments, Livefyre, Trackbacks to wordpress.
If a user is required to create an account with your site before they can comment, you might as well ask them to fetch you a soda from mars. It’s probably not going to happen. However, if you can give them the option to comment with an account they’ve already set up, then you will be much more likely to get some interaction.
Version 1.5 brings rebranding to Comments Evolved name as well as many code improvements, a shortcode for displaying the comment section, groundwork for showing comment counts ( not yet 100% complete due to a few performance concerns ), and a new Github repository for those of you that would like to contribute to the development. A complete change log can be found here.
As always, feel free to drop a donation at WePay if you can and let me know what you think in the comments below, Also be sure to get in touch if you would like to contribute to the Github Repository.
