Hey, Just a thought. I'm not sure what the legal standing of warrant canaries (i.e. being compelled to lie) are in Canada, but given the privacy level afforded by the site the key component to that privacy is trust.
You're doing a lot to make sure private data is treated as harmful, and with the open source code being visible, but that's still not a guarantee that the server is actually running the code that will be open sourced.
Tildes could probably benefit from a warrant canary given that it's a platform for user generated content and if it gets prominent enough it may be subject to LEO scrutiny. Compliance with LEO is a given since the website operates under Canadian Jurisdiction, but given the... nature of some requests (Gag Orders / Etc...) a canary could be a privacy positive move for users of Tildes.
