I wish the default Lemmy client wouldn’t interpret text as a URL so aggressively. The workaround is to preface the period with a backslash, like so: sentence\.be

Relatedly, when I post raw links, I sandwich them in < & >, because sometimes the client won’t interpret the text aggressively enough such that some of the (usually long) URL fails to be included. The angle brackets don’t get rendered. Example: https://github.com/lemmynet/lemmy-markdown-it-plugins

Its a feature of the markdown library we're using in lemmy-ui (markdown-it) called linkify.

IMO the benefits of it outweigh the negatives. Its nice to be able to just type hexbear.net or something without having to add the https:// every time.

Not an issue, the client has to recognize possible links.

As the other comment mentioned, you can edit the text to fix grammar errors.

you can just edit the post. it's not a problem
