Ok, You guys have been opening my eyes. I'm finding there's more BA than TV, Movies, Books and Radio. One of my loves in my life right now is surfing for information on the net. My diseased mind keeps saving favorites and bookmarks. Probably very unhealthy but I like to surf back to sites and check for 'latest' news.
I need some guidance so If you could, would you please answer a few simple questions?

1) I have 14 science, 8 space and 6 exploreAll folders in my favorites, many of these folders hold inexcess of 50 sites related to the folder designation. Overall I have close to 4000 sites in my bookmarks. Does anyone else have this issue?
2) Can I start a thread to verify the validity of my 'space' related sites?
3) Can I consider any sites pre-valid? (NASA, Colleges, DOE)
4) Would this be a fun thing to do to explore 'whats out there'?
5) Is this post out of line?

Yes, I am serious. My NASA folder alone exceeds 75 sites in NASA's domain.

M87 Quasar jet travels at 6 times the speed of light

Is this for real?

Jets from quasars can appear to be superluminal even though they're really not. It has to do with them facing almost directly toward or away from us. See here. (http://spacescience.spaceref.com/newhome/headlines/ast24nov99_1.htm)

In any case, the references the guy provides don't say what they claim he says. None of the refereed papers are claiming true superluminal motion.

No, I only book mark the really important ones like BA for quick access. If I find something interesting I try to remember how I got there so I can get there again (usually via google) from anywhere (one day I'll sort out some sort of roaming bookmarks :) ) I use firefox's "open in another tab" feature so I can browse and flip between different links I find at my leisure.

2) Can I start a thread to verify the validity of my 'space' related sites?
I can't speak for the site but I can't see why not. Doesn't sound offensive, and people are free to not read whatever threads their hearts desire.

3) Can I consider any sites pre-valid? (NASA, Colleges, DOE)
I guess there's some, but you develop a knack for sniffing out for yourself what's against the mainstream, a rant, woowoo, etc. For every site ask yourself "does this make sense?", "what's their agenda", "is it a mile long page of yellow writing on a black stary background?" That last one is a dead giveaway for most woowoo sites out there. The first one is really important, it is up to the author to get their point across, not up to everyone else to divine what they actually meant - if they have something important to say they should say it clearly, without reams of inuendo and asides about the powers that be etc.

4) Would this be a fun thing to do to explore 'whats out there'?
Yep, isn't the Internet great!

5) Is this post out of line?
Why would you think that?
