I used to do some livecoding myself. The answer is that it depends on the specific things you are working on. Some thing lend themselves very poorly for livecoding, but others work out pretty well.

For example, if you are doing interview practice, for Google style interviews, livecoding your interview practice is actually a pretty good experience.

Coding in front of an audience isn't much different than coding in front of an interviewer, if you think about it.
