There are lots of sites out there that let you create virtual “corkboards” and you can see them at The Best Online Virtual “Corkboards” (or “Bulletin Boards”). Padlet (formerly known as Wallwisher) is probably the most well-known tool of this kind.
Like the best of the other sites, you can create these bulletin boards easily without registering and you can collaborate with others to create them.
Two features, though, that Stoodle has but, as far as I can tell, others do not, are:
* the ability to search and find images on the Web within the application itself. With the others, you have to find an image in another tab and then paste the url address into the site. Stoodle gives you that option, too, but searching within the site makes it a lot easier.
* The chat feature between collaborators is text and audio. I don’t believe any other similar tool as the audio chat feature.
The only two negatives that I see are:
* unlike Padlet, you can’t embed a Stoodle board.
* Using Stoodle the first time isn’t as intuitive as Padlet. It would be nice if they had a short video or just some screenshares identifying how to use the icons. One can figure it out in a minute or two by playing with it, though. Just note that in order to move around the virtual “post it” notes, you have to first click on one of the icons on the left.
I’m also adding Stoodle to The Best Online Tools For Real-Time Collaboration.
