I’m still amazed how easy it is to get content onto the web today. A few clicks of the mouse, and you’ve got yourself a blog/twitter/facebook account ready to go. Whilst there are downsides to this (i.e. a lot of spammy content), the benefits definitely outweigh the drawbacks. It doesn’t matter what your area of interest is.
– Looking to learn origami? There’s a site for that.
– Want to know the ins and outs of poker? There’s a site for that.
In fact, you name it, you can probably find a site for that. This is the digital renaissance people
What do I use? I tend to favour Word Press if I’m not trying to do anything too specific. It’s not perfect, but it’s easy to use, easy to set up and would be my #1 choice. I work as a web developer for a living and have a custom built CMS, but Word Press has everything in a box ready to go. The plethora of plugins (say that 10 times fast) means you’ll almost certainly find something that will do the job.
