I like that it is simple enough for anyone who just wants one place they can bookmark things or links that are important but not something they want others looking at their computer seeing when they're searching in Google (or whatever).
It's easy to use also so no need of training if your new to using an app as well as its free which makes this great to start with since there isn't any cost involved (unless paying monthly subscription fee) unlike other services out there. Nothing really dislike about this service either; however, sometimes the website will load slower than normal browsing speed because we have limited internet data usage per month. Try it out first before deciding whether or not you would be comfortable sharing what sites you've been viewing/reading online without having people see them when someone else browses through those same pages you were reading previously.
