Two spaces after a period is a typesetting anachronism. That said, I typically do just that, as it is how I was trained.
The problem with that is the lack of consistency. APA guidelines call for two spaces, while the ACS format I use does with just one. Most journals that I know of call for a single space although to be fair, I deal with science journals rather than liberal arts publications, so I can't speak to them.
