Loockerman Street, the main commercial street.
A few weeks ago, a coworker asked me to let her know what the soups were for that day at 33 West, a very popular eatery (my favorite, in fact). I was thumb-typing the list of soups into my cellphone to send to her when I thought, "why not put this out via twitter? There may be other folks trying to decide what to have for lunch." So I tweeted the soups and lunch specials.
I did that a time or two more before I realized that it would be easier to simply snap a cellphone photo of the specials board and post/tweet that.
So began an occasional habit. On those days when I do walk up town, I stop to snap the specials boards of the two lunch places that routinely have them -- 33 West and the Dover Newsstand.
The Newsstand, it should be noted, does post its specials each day on its web site. That's a good practice, though I think it would make sense for restaurants to routinely post their own specials to their own twitter accounts. Twitter is a "push" medium; it goes out to all who subscribe (or follow re-tweeters), while a web site is a static thing and of no use unless someone is specifically looking for it.
So, if you are in Dover and wondering what to have for lunch, I invite you to check my twitter-stream. It won't be every day, but on many days, I'll post links to pictures of the chalkboards that will tell you what's for lunch.
