Is it true that you can't see tweets that are posted here at DU unless you have a Twitter account? [View all]

I'm pretty sure I've read comments to that effect, but I don't understand why that would be the case.

I've had a Twitter account for years but never used it much. I just never found it enjoyable. It's too big and impersonal, and writing tiny short posts is just not my style.

Now that You Know Who has taken over, I've seriously thought about deleting my account. But I don't hat means I wouldn't be able to see the tweets people post here, I'm inclined to keep it, at least for now.
That is really the only thing I use Twitter for these days, but it's something I would really miss.
