Blogging is usually a way I talk to people I don't otherwise talk to. Not that friends, family, clients, and staff don't read it -- I know you're there! But there is another group of people I know are reading who I don't normally email, IM, call, see, or send pieces of paper to. And in my life, as in so many lives, things come up, stresses rise, deadlines loom, project work eats all available hours, and the blog starts to suffer.
It starts with missing a few days, then catching up. The "stuff to blog" file is handy here, so when you catch up you clean out the file. Then the number of days you're behind exceeds the number of entries in the file, and besides most of them are just a link and you don't have time to write the three sentences that go with it. So then you don't blog for a while.
When are you likely to start again? When the blog becomes the more efficient way to talk to the people you usually talk to, but don't have time to. Expect the blog to get a little more personal for a while (though there's some technical stuff to clear out of "stuff to blog" as well, or to go dark again. I'll do what I can.
