Use the opportunity to write several posts when you’ve got inspiration. That way your, hopefully, steady stream of posts will make it through times when you lack inspiration or time to write posts that are good enough to publish on your blog.

Most blogging tools lets you set a publish date in the future so if you are going away for a couple of days you can keep the flow of your blog anyway.

This practice is even more important if you have decided to write a series of posts because it will be easier to make them stick together. If you are writing a series and have some research to do for the later parts, at least mash up as much as you can of the future posts to keep them in spirit of the first one.

Having some canned posts can actually make it easier to write since you are relieved of the stress that can come from feeling forced to write an article just to keep the flow going.

In Wordpress it is possible to save drafts for future editing and publication. Before I started using Google Documents for my future posts I used the drafts in Wordress a lot.
