Wordpress is flexible, but you'll need to stay up-to-date on security updates, make sure your blog doesn't fall over if it's popular on HN, do something about spam, etc. If that's not your cup of tea, consider something hosted (tumblr, posterous, wordpress.com) or something simple (static site generators work fine, see p4bl0's comment.) This may or may not matter: tumblr is free, conventional hosting (Dreamhost, cheap Linode) will run you ~10-30/month, and pay-as-you-use hosting like nearlyfreespeech.net can be extremely cheap (especially with static site generators). I'm using the latter option, for what it's worth.
