I don't bother submitting stuff any more because:

1) There's too much noise on the new page.

2) It matters which at what time of day you submit an article.

3) There's too much chance about whether it'll been seen or not.

4) Someone else will post it with a slightly different URL (see above), and that's the one which will be noticed.

I am, of course, very grateful for everyone else who posts stuff. There's usually a good article or two on the front page.

I suppose the question we should ask is if it matters if decent articles are missed? There's lots of text out there on the internet.
