Cons
Con In alpha
It's still early in development and parts of it may be buggy.
Con So far impossible to delete account
Menus only give option to deactivate, not delete account. Can't log into helpdesk with main account credentials (as it says you should), so no way of tracking submitted ticket. Deleting account should not require helpdesk input.
Con It is slow on Chrome web browser
A new tab opens slower than on others.
