Diigo Review

October 4, 2007 at 2:48 pm by MTS

I have been working with Diigo over the past day or so in order to test out its functionality.  In summary, this applet will someday be a great tool for us to use in prototypes, but the number and nature of Diigo's bugs prevent it from working well for Newfangled.

Diigo is a wonderful tool, overall.  The features it offers are pretty amazing.  I anticipate Diigo will revolutionize the way some things get done over the Web.  It has some setbacks, though.  These are the bugs and/or tedious things I found:
  1. In order to use Diigo using the Diigolet, a user must click the Diigolet button every time a page loads/reloads.  Yesterday, Eric discussed the possibility of having our clients use the Diigolet instead of the Diigo toolbar.  This would make things much simpler for the client.  However, the necessity to "restart" the Diigolet on every page in order to view or make comments is a setback.
  2. The client must share the comments/highlights he makes with the right group.  This only has to be done once, though.  I had a problem with this in the Opera Diigolet.  After selecting one group and making a comment, I reloaded the page.  The next comment I made had "all listed groups" as the default.  I do not know if this indicates that the default group will ever be "no group," but I cannot figure out why the default group in the group sharing dropdown would have changed.  You can't make comments/highlights public until you have two friends in the Diigo network.  From http://www.diigo.com/help/stickynote/2 : 'A "friend" in the Diigo community is a member who joined upon your invitation or who invited you to join.'
  3. I was automatically signed out of Diigo twice yesterday.  Not sure why...
  4. I deleted a comment in Firefox, but it was still visible in IE7.  When I deleted it in Opera, it was finally and permanently deleted.  Deleting comments doesn't always fully work--sometimes they reappear after reloading a page.
  5. Highlighting a phrase that appears several times in a page will cause other browsers to see the first instance of the phrase highlighted.  They will not necessarily see as highlighted the phrase you highlighted.  Diigo is aware of this, and is working on it.  See http://groups.diigo.com/Diigo_HQ/forum/topic/837 (June/July).   See also http://groups.diigo.com/Diigo_HQ/forum/topic/95 from April.
  6. Comments don't always appear in the same place on the screen in different browsers.  See my post at http://groups.diigo.com/Diigo_HQ/forum/topic/1506.
  7. Sometimes the buttons on the Diigo toolbar don't work.  For instance, if I'm browsing around at www.online-guitar-sale.com and I want to write a comment reminding myself to make the first picture (guy with the guitar) smaller, clicking the comment button on the toolbar doesn't seem to do anything.  Similarly, when I triple-click to select an entire line of text, the highlight button wasn't working on that page.  I can still right-click to add highlighting.  I'm not sure if this button defect is always the case or not.

I suggest that we do not use this for our client note system in our prototyping process. It has too many bugs that make it useless for our application.   We can reevaluate the next release when it comes out.  I have applied to preview the next release, which should be available on a sign-up basis in a few weeks.
