Update Frequency

More updates are certainly better. With frequent updates the reader is constantly reminded of the characters and story. On the other end, it's unadvisable to go long periods without an update; the story line and characters can be easily forgotten. A balance needs to be found between frequent updates and your ability to produce the material.

You should never be posting strips immediately after they're done, you're just tempting fate. Without a few strips already prepared or some leeway in producing the strip, a small delay will propagate. The best scenario is being able to work slightly faster than needed, so a buffer is developed without interrupting the updates. A few days/weeks buffer is always beneficial; equipment failures, writers block and other obligations are just waiting to strike. As an extra bonus, it gives you time to proofread or modify finished strips.

When updating four or more days per week, the time of update becomes important. If both the time you update and the time the reader checks remain constant, a new comic will be seen each day. Otherwise the reader has to determine if he missed one and, if so, check the archives. Too bad if the current comic is a spoiler.

For the final note the week, don't change update schedules often. It's often better to place everything on hold, take care of the problem, rebuild the buffer, then return to normal updates than spend weeks or months in a slowed state filled with missed updates.
