This is awesome.
Could someone design a sticker sized format? Approximately 1x4 inches. Im not sure about other places but where I am in the UK, people seem to like to feel they've discovered something, rather than shown it.I also feel no one I know would read any kind of notice board. Just a very basic sticker with the logo and something along the lines of "steemit, get paid to Facebook!". You could stick them to hand-driers in cinemas, restaurant, bars, pubs and clubs (anyone who doesn't wash their hands, you don't want on Steemit anyway). Most of these type places have paid advertisement boards so you can't just put you own A4 flyer up. This could give a good second option. Would make a good bumper sticker too.
Just a thought.
I'll print off 5-10 and ask a few people if they can put them on notice boards in the local supermarket and office tea rooms.
