The most common mistake with wireframes is not tailoring the output for the internal audience - that is those that need to use it.
Unless working for the same company / people / process each time then the same deliverable is unlikely to be right for all situations.
Additionally there are times when annotated designs or mid fidelity prototypes are best or, in other situations, a sketch on a whiteboard might all that is needed to get the work done. If wireframes need to be highly detailed it may be a sign that UX and engineering are not working close enough together.
