I am thinking of building an iotCloud for hobbyists. So users will get a link which they can post data to via REST/MQTT and their data will be stored in a database which they can access via a web front end.
Would be super easy to use and would provide a great feedback look for all the hobbyists out there experimenting with iots. Just wanted to see if there was interest in such a thing.
PS: I searched around for one for my personal use and was pretty disappointed in what is currently available.
