How helpful is it to bookmark a Web site if you need only one sentence from that 3,000-word article? Diigo is a free bookmarking service that lets you do what we wish Yahoo’s Del.icio.us would: highlight text and comment on Web pages. Diigo caches each site so that you can search within text, not just the topic tags. And you won’t have to leave the Del.icio.us community, since Diigo lets you save bookmarks simultaneously in both places. CNet
One thing about Diigo. One gesture to Diigo can simultaneously update all your other bookmarking sites. That may create a lot of duplication, or it may create the opportunity to connect with others across a world of tagging that remains fragmented. I shall continue experimenting with it.
Recommended Tool for Feature-Hungry Technophiles: Diigo
Diigo has everything I’ve been looking for in a great social bookmarking/collaborative research tool—except ease of use. The tagging system is still buggy (renaming a tag or deleting it can lead to unexpected results), and the interface has some usability issues that I’ve already discussed with one of Diigo’s co-founders. For instance, tag clouds only display the first 18 characters or so of each tag, preferences on how to view your tags revert to default settings every time the page refreshes, etc. Unfortunately, Diigo is still too frustrating to use for me to recommend it to non-tech-savvy educators, but I hope its shortcomings will be resolved soon. If that happens, I’ll become a major Diigo evangelist. If not, I might have to embrace a more bare-bones bookmarking tool like Del.icio.us and search for a separate tool that just handles collaborative research well. Google Notebook is next on my list of tools to check out for that.
