There are two prevailing approaches to editing an existing question or answer:
- Marking the edit with a keyword such as "edit" or "update", or setting it off using bold or italics.
- Blending it into the existing text seamlessly.
Since we have many frequent repeat visitors, yet the majority of a questions views accrue slowly over time, I suspect that many new people come to this site all the time and check out plenty of old questions, perhaps more so than the typical stack. For the dual benefit of the site and the broader Internet, what is your opinion regarding what our approach should be?
I posted answers below for each possibility. Please up vote your preference or add your own.
