I see a lot of blog evangelism, so I'd thought i'd do one for wikis. If you want to put stuff on the interwebs but find the serialised blog format not really your thing, try a wiki! Basically, each page represents a topic that is gradually added to and edited as you find more things to say, instead of being tied to a specific date.
Personally, probably bc of adhd, dates don't mean much to me, something I haven't touched for 3 years is as relevent as anything else, so I find wikis useful.
