The content of the following platforms is completely consistent and serves as backups for each other.
Twitter: (Discontinued. No API, limited character count, limited access)
|Nostr||No character limit found at the moment.|
|Telegram||Character limit: 4000|
|Mastodon (Mammoth)||Character limit: 500; No plans to self-host|
There are currently no plans to establish mutual links. Personally, I believe that mutually following each other on social platforms is sufficient (the social platforms I use are mentioned above).
