I've kept various forms of blog over the years from personal "just to keep some notes" to a company-related journal. I've been hopeless at posting regularly to all of them and, as a result, they have withered and died.
The whole corporate journal thing really doesn't appeal to me much anyway. If I'm going to post to a blog then I really don't want to have to think too hard about it. I've also always felt very uncomfortable posting anything of personal interest to it for fear of "losing" it if I ever change job.
I doubt this blog will do much better (I've not even convinced myself that I want to use blogger.com yet) but it really is about time I posted about stuff I'm interested in, stuff I play with, etc.
