i guess you don't HAVE to use a rec as a rec, but maybe have a third option other than rec and ask. maybe just call it thoughts? for when you have a thought or a feeling that you want to share but it isn't a recommendation.
maybe having an anti-rec option under recs, too! like a drop down when you do choose to make a rec, you can choose to anti-rec. make sense??
lastly, having changing your email/password built into the settings. i ran into this the other day when i put my email in wrong and had to get ahold of you guys!!
