I had been using 
username to help me keep on track sensible things about steeming like, who mentions me, who followed, who upvoted, who commented, the price of steem, sbd internally and in exchanges, and your 7-day earnings too, etc.
You can explore it and I think it is one of the best steem-based site to help us in our blogs to keep on track and never miss notifications anymore. You can also vote from there, vote for your witnesses, send some delegations which is convenient as it gives real-time info regarding steem data too that is relevant for your steeming needs.
It is better to use it so that you can have a much better steem experience and never miss out again about your notifications. I just hope that it will improve into a much better site but currently it serves a good purpose for all steemians big and small.
