Reporting/Journalism 101.....here goes.....
Cite your sources, confirm your information. Because anyone can write anything on the internet and say it's true, accuracy and legitimacy is a must. If not, you'll start reading news items based off hearsay "I was told" "I heard" "my good friend."
I'm not trying to bust anyone's balls here, truly, I'm just sick of reading posts and entries from people who say they have pseudo-official knowledge but are unwilling and unable to produce any kind of corroborating evidence or contact info. Obviously, part of this comes down to deep throat contact who wish not to be named (which strangely is always the case lol).
When I was about 23, I had a dumb little online newsgroup called The Viper Pit, which I started as the build up for Alien Resurrection began. I was contacted by Kerry Shea, a visual effects coordinator on the show. She gave me some awesome information that I was able to share with everyone involved with the zine.
I've read several postings in relation to Prometheus so far, posted by earnest and excited individuals citing a secret unknown source and to be taken as gospel, all of it based on their word. You'll have to forgive the gratuitous amount of skepticism on my part. I don't think it's particularly ethical or fair to excite or disappoint a rather rabid fan base with knowledge that cannot be confirmed except on the word of the unknown, faceless poster.
But maybe that's just me.
