[Need Sugestion] wordpress as blog or keep using CI?

[eluser]PhilTem[/eluser]
I can only endorse @CroNiX: Why reinvent the wheel? Wordpress is a huge and powerful blogging-software. It evolved over many years and got almost no more security bugs or other "bad things". If you coded a blog by yourself, you probably will end up fixing the scripts over and over again and won't get time to write any posts.
When it comes to creating a presentation page or a platform for my page, I use wordpress as a first choice over Joomla or some other CMS, since it's easy to set up and has almost everything you need shipped directly within the downloads. And it's super easily extendable with plugins and easily integratable into CI as well.

Conclusion: Go for worpdess

PS: You may as well develop a blogging software based on CI just to get the power of CI but I wouldn't recommend using it as a production site if it's not super duper developed
