I want to love this app, but...

It's slow. The web app is wonderful. When I add or remove a bookmark on my iPhone or iPad, it shows up on the web within a matter of seconds. When I add something on the web, nothing happens in the iOS app, and if it does, only after I refresh, and that seems to take an unusually long time pretty much every time.

In the iOS app you have an option that we can select to save all contents as private. What I would really like is to also have an option to save all bookmarks as unread as well. This is crucial if I'm going to select the option to quick save without a bookmark window. When I save bookmarks for reading later, I want this to be a quick process that will be easy for me to find what I bookmarked for reading later.

Technology Class

I was assigned to use Diigo for a graduate technology integration class and I have been very impressed with the functionality. I liked the option that synced the online version to the app. I was able to pick up where I left off when I got on the bus to go home. The tags make it easy to find related articles. I would highly recommend using this resource for higher ed learning.

NO,you DON'T get my email to spam me!

Read a really good review about this browser. So, I installed it and before I even got a chance to see what it was about it required me to sign in. That's boolsheeite. Like someone saying"here, whyowntcha just bend over, grab your ankles and lemme take a look atcha nawty-bits? Trust me, plus it's only one finger.
Don't simply and blindly give someone information just because they ask. There are plenty of other browsers that don't require your information. Don't be a naive fool.
