THE PEOPLE HAVE SPOKEN. The pipe character "|" is by far the most popular page title separator with 47% of the vote and being up against 15 other choices. Example:
Article | Category | Site Title
The dash and en-dash split another 24% of the vote and then the rest fought for the scraps. I'm in agreement. I like me some pipes. My second favorite is the middot. Not as intense as a bullet and without the baggage of a period. There is a permanent living archive of all poll data.
New poll will be up later tonight or tomorrow.
