Yes, that would ideal way to use twitter. But most of the people don't use twitter for that. For example, Mashable has 4.3M followers, what they do is tweet every 15 minutes or so with their links, sharing a link multiple times. And for these 4.3M followers those, the kind of tweets you mentioned will get buried among these tweets.

But its very difficult to separate the "less useful" tweets. For example @pmarca shares a lot of links always accompanied by some comment. But a lot of people share just the title and the link and can be considered less useful in a sense that it should be displayed in a list like in Delta.

Still that's a great idea, and increase the utility of twitter for a lot of users. I never thought of that. Thanks.
