I assume you're here because you've been reading talk.bizarre and want to try posting things that will be well received. Actually, if you have been reading talk.bizarre, have even a scrap of writing skill, and actually have something to say, you probably don't really need any guidance. Just post it.
So I assume you haven't been reading talk.bizarre, but still want to post to it, and have been told that it's a real tough gig. Some of the suggestions below may help you hone your craft, or at least dissuade you from posting something that will enhance your collection of terminal description database files.
Every writing course ever taught has hammered on the phrase "know your audience". You can't "write to your audience" if you don't. So, what are talk.bizarre readers looking for? Bizarre articles, what else?
Damned if I know. If it could be described, it wouldn't be. That's a hint. Originality goes a long way, though.
That's somewhat easier. A large portion of the talk.bizarre audience has been on the Internet essentially forever, ever since computers ran on steam power anyway. So, anything that has been on the Internet essentially forever is likely to have been DONE already, hence is not bizarre: "smileys", "net celebrities", geek jokes, that kind of thing. A much larger portion of the talk.bizarre audience is at least 7 years old, hence is likely to have been inundated with such cultural icons of the formerly-bizarre as Monty Python (all the shows are available in book form as scripts; you call that new?), and whatever comic is hot on TV this week. And nearly all talk.bizarre readers are capable of reading other newsgroups, so any material that could belong in another newsgroup, especially anything that belongs in a newsgroup containing the name CONFIG, FAN, FLAME, HUMOR, IRC, MISC, RELIGION, STARTREK, or TASTELESS, is not appropriate for talk.bizarre.
And because talk.bizarre craves originality more than anything else, posting the unattributed work of other artists will get you crucified.
The talk.bizarre voting page can show you what some people, those who bothered to cast votes anyway, liked in the past month. If you want to become talk.bizarre's next rising star, go study those high-rated articles carefully.
Then post something completely different. But just as well-written.
Of course, if you are just compelled to write, then you will write, regardless of any suggestions. The Muse That Cannot Be Stopped is often the best possible inspiration for a talk.bizarre article. Of course, if it's really just The Monkey Gibbering In Your Ears, we'll let you know.
