Pinside is a very easy to use online “corkboard” or “bulletin board” where you can “pin” notes with text and images and then mix them around on the board. The problem, though, is that there is no way (or, at least, I couldn’t find a way) to make your board public — they are only accessible to people whose email addresses you list.
That is a major shortcoming, one that the other tools I list on The Best Online Virtual “Corkboards” (or “Bulletin Boards”) don’t have — they all allow boards to be public.
Maybe that’s a feature plans to include in the future. Unfortunately, their site doesn’t list any way to contact them to find out.
