Most coders I know use ampersands in meta content to reduce the number of characters.

However, w3c compliancy requires using "&" in place of "&" which defeats the purpose (having less characters for "and").

So use "and" instead of "&".

If you don't care about following w3c validation regarding meta content, e.g. the title, description, etc..., then use "&" in meta content.

Some browsers display "&" correctly in the description, others do not.

I prefer using "and" to avoid these potential problems.
