A nice way to share a group of URLs is to “box” them together using a service such as Simplybox.
If you are new to Simplybox you can watch this overview here to get an idea of what Simplybox is all about.
Once you’ve added the webpages (you can tag and describe them) then you can choose to share the box publicly via URL or by embedding a widget – shame this doesn’t seem to work on Moodle or edublogs but it does look great on a wiki!
Another nice feature is the print options. If you select “view as list” then choose print (e.g select pdf) you can create an archived version of the comments on that selection of webadresses.
In comparison to using Diigo, I’d say the pros of Simplybox are that the boxing is simple and user-oriented. You can save the part of the website you want to “capture” by dragging your mouse over the area. This can help visitors to see the part you are pointing them to.
One of the drawbacks, is the person doing the bookmarking needs to add another bookmarklet to their browser.
What do you think? Have you got any feedback from students/trainees?
