I think the secret to blogging frequently might well be not having a job... I occasionally pick up pieces of consulting work or sponsorship but I'm mainly working full-time (uncompensated) on my own projects.

Link blogs are different though: posting to those genuinely takes a couple of minutes per link. I've maintained my link blog happily while having a full-time job.

We could automate the link posting process. Here is a thought, create a form which accepts the input of link details, stores in some place and ur website reads and displays from there. Submitting a form could be simpler and can be done from any device.
