For all of you suspicious minds out there, no I am not creating another platform for blogs, I really do need one for my product.
Thank you !
On the down side, it requires constant security updates, and has a bit of a learning curve if you're trying to customize it. (It's also in written in PHP, which is a big problem for some people).
I've used it on my personal site and many work projects and found it to be great as long as you're willing to pay attention to updates and find/install plugins that fit your site.
A properly set-up blog will hold up to a front page Digging/Reddit-ing even on a cheap host.
