Spike,
Glad to hear you're still enjoying things. We're getting very, very excited for our v5.1 release (which should be out next week). That release adds Google authentication, and a whole bunch more. It's going to be big.
As for your question, I'm sorry you ran into some issues with the EasyBlog integration. My guess is that you're running into a problem we've heard of, but haven't fully diagnosed. To fix, you can either disable the Open Graph - EasyBlog plugin, or you can edit the /plugins/opengraph/easyblog/easyblog.php file. Around line 121, you'll see:
if ($image_type == 'custom_image_category' || $image == '')
{
$tmpImage = SCArticleContent::getEasyBlogCategoryImage($item->category_id);
if($tmpImage != '')
$image = $tmpImage;
}Comment (or delete) that whole block out and that should prevent the error. We'd love to know if that helps.. and if so, could you let us know what version of EasyBlog you are using, which may help us narrow things down further.
As for EasyBlog, no arguments there, it's a great extension. We use a mix of Joomla articles and EasyBlog (for our blog) on this site, actually. Joomla articles are easier for documentation and 'static' content, in my opinion. It's usually simpler by default so there's less to actually disable than if we were to use EasyBlog. Plus, many extensions work directly with Joomla content, which is a benefit.
In general though, using EasyBlog exclusively for content isn't a bad thing. We're working on even more integration with EasyBlog in addition to our existing features, like posting when an Open Graph Action whenever a user leaves a comment to their Timeline.
I hope that helps answer your questions, but if you have any others, just let us know.
Thanks,
Alex
