I don't submit much, but doesn't the text section of a link submission just get posted as the first comment?

I don't think so, since most of the submissions I see have the text appear as the body of the post and not as the first comment.

From the FAQ:

> How do I make a link in a text submission?

>You can't. This is to prevent people from submitting a link with their comments in a privileged position at the top of the page. If you want to submit a link with comments, just submit the link, then add a regular comment.

I'm just saying what I actually see in postings here. I don't make postings myself, so I have no special insight beyond what I see.

You should articulate an actual reason please.

Bit of a weird take, though agree that for most submissions the Title content should do most of the talking. Sometimes it's nice to know why OP is submitting the link especially if not a news item. Knowing what caught their eye about a link or a bit more context is useful but does it need to be the overarching Text section? A comment below should suffice, and also starts the discussion there on whatever point they are drawing attention to.
