I was a subscriber back when it was SteemSQL and I can attest to the stability of what you offer. Furthermore, what you offer allows running some substantially powerful and long queries, the kind that you couldn't query the blockchain itself (not without some tricky engineering a whole lot of Hive Power).
I would love to see @blocktrades and other heavy hitters in the Hive ecosystem support HiveSQL because the possibilities it allows from a dApp perspective are severely underrated and worth paying for. Not having to manage hardware, servers and sync your own database is worth paying for alone. I will be disappointed and disheartened if the Hive community doesn't support this proposal and make it happen.
Just letting you know @arcange that the second link for the proposal on Hive.blog appears to be broken as well.
Thank you for your feedback about your experience with HiveSQL (formerly SteemSQL) @beggars 👍
PS: hive.blog link fixed. Thanks for notifying me.
