Posting an ad on craigslist to sell your mattress and the foosball table for which you will have no space in your new condo, you find yourself engaging in all the classic behaviors of a first-time poster on (ahem, not that I know what that’s like, but I have friends! Friends who have online dated!): refreshing the craiglist page for 15 minutes until you confirm that yes, your ad has posted, then refreshing your email every 30 seconds because why has no one offered to buy your incredibly low-priced foosball table already? People! This is a bargain! Get on it!
