Many code news
There are fashions in the markup world. There was a time when using
colons (':') to split fields in /etc/passwd was enough,
a time when no one had a problem with using TABs as command
delimiter in Makefiles. Then came the era of heavy
markup, "more semantic!", they all asked for, and we received XML.
More semantic is a good thing but anyone who wrote documentation using DocBook knows that the heavy syntax gets annoying really fast. No wonder no one documents his programs. Fortunately, some lazy programmers wanted, for some obscure reason, to document their programs; they propelled us into a new era of light weight markup.
There are quite a few really good light weight markups out there, and Gazest supports most of them. For simple formating, my favorite is definitely Markdown. It reads like text emails: the syntax doesn't do much but the essentials are there and the syntax actually helps to read the source instead of obfuscating it. For blog comments, or anything that won't need much semantic, in applications where you can't use for HTML, for security reasons or just because it's a pain to type, Markdown is the way to go.
