pros:
the project is useful because it makes us to have more information about steemit tags and it makes us understand them better
the project is an open source and that makes it more interesting because it means developers are welcomed to make the project better and more successful and that is great for the future of the project
the interface is lovely and gives a well detailed 3D data information..
cons:
you might need a large internet data connection for you to effectively use this app because of its consumption rate
In my opinion you need the same internet connection also the other Steem DApps.
