Just to double check, I also used the feature on my profile page, allowing me to view it as him - to see what he'd see. I double checked my privacy settings, friend lists, etc. I don't post pictures of myself that are embarrassing or compromising, anyway, so that wasn't an issue. As a rule, I don't say anything on the internet I wouldn't want the internet to see - and that includes any new people in my life.
About 20 minutes after I did all this, I got an email from How about we, with a link to an article called 9 Things to Do When Someone You Like Friends You on Facebook.
Honestly - the tips are really what everyone should be doing anyway. I mean, wouldn't you always show off your best self, crush or not? Things like checking the top five photos, and watching what you post on others pages, and carefully choosing which pages to "like" - that's all normal facebook activity.
Always show off your best facebook face.
