I have heard alot about both of this CMS or blogging software or what ever you guys called it, and I have download both of them as it is a free stuff, and both looked quite perfect from my point of view the features seem to be the same, as I am about to launch my personal site etc, so I am seeking some guide on which one of this should I choose, I know quite alot of people been using Wordpress, but still I am wondering what so good about it?
Go with whatever you feel most comfortable with. It sounds like you'll be the only one editing anything so it's really up to you. I've seen a lot of wordpress out there and I've heard a lot of good things, but I havn't heard of nucleuscms.
They are probably both very good CMS scripts, but I have been looking at using Nucleuscms for a client of mine and I think there are more addons available. So it really depends on your preference and what features you need available to you.
