Blogs, Twitter, and Diigo or Delicious

Each technology has its own limitations and attributes.

Blogs are a great way to post information in an ongoing format that is easy for everyone to see and comment on. In essence, the "announcements" section of our Blackboard is a fantastic example of this. Likewise, I used a blog-type format for informing parents of events that worked well when I was school teacher. I think Blogs are one of the best Web 2.0 tools and am excited to use them more often.

Twitter has its advantages for informal learning. It is an easy place for people to ask questions (as illustrated in another post). It can be a good way for teachers to send quick bits of small amounts of information (i.e. "midterm due next week"). It has a lot of limitations in its short amount of characters it allows.

Diigo and Delicious are fantastic ideas for people to save information around the web. For example, a teacher who teaches a course on instructional games can save all the websites with good information, websites with actual instructional games, and anything else in one place that students can access at any time. Likewise, smart students can save information they think will benefit them later in one place on their Delicious page.

My only question is that I have found Delicious to be more helpful than Diigo, but Diigo boasts several reasons why they are better than Delicious and people tend to like Diigo more than Delicious. I would really like to hear why Diigo is better so I can be sure to use the best technology. So, if you like Diigo more than Delicious, why?
