A blog is not a blog unless...

Scoble quotes Dwight Silverman, of the Houston Chronicle.

He says:

What made blogging better than Web sites? Five things.

1) Ease of publishing.
2) Discoverability. (Pings weblogs.com or technorati or another ping server).
3) Conversationality. (Trackbacks or as-they-happen referer logs, or now being part of Technorati and other blog search engines).
4) Linkability. (All posts should have permalinks).
5) Syndicatability. (All content should be available in RSS feeds).

If you don't have those five, you shouldn't call your stuff a blog. Especially if I can't link to it from here.

I agree.
