Party Down. The comic brilliance of Jane Lynch, Rob Thomas, and Paul Rudd and excellent supporting cast plucked from Veronica Mars (also an excellent show).
You’ll be impressed to know that I once went to a costume party as The Badger. Yup, it was an obscure costume, but it was appreciated by the hepcats.
Increased demand drives the prices up. 
Robert Charles Wilson - Great SF author. Doesn’t get the attention he deserves. Probably too Canadian for American readers or something.
Elementals - People lavish all kinds of praise (deservedly) on Alan Moore and Frank Miller for re-inventing the comic book genre in the eighties. But Bill Willingham deserves a lot of credit too. His Elementals was being published at the same time as Miller’s Daredevil and Moore’s Swamp Thing.
Well, since you asked. One day she will be, not just known, but respected and revered among musicians, musicologists and serious music fans. It may not be in my lifetime, but it will happen. Her music over the course of 11 albums is too good, her voice is too phenomenal, her story is too fascinating, to stay obscure forever. The fans who’ve already discovered her or discover her now are very lucky indeed.
Able and Baker, which is just a gag-a-day funny animal webcomic. It is, however, one of the best examples of such.
The work of Shaenon Garrity. She’s fairly well-known in the webcomic world, which puts her mainstream fame somewhere above Gauss’s and below Tron Guy’s. She focuses on online graphic novels, by which I mean webcomics that tell a single long story from beginning to end and then stop. Narbonic is how she broke into the webcomic world’s vision and Skin Horse is what she’s doing now; Narbonic has ended and Skin Horse is ongoing. Read Narbonic first.
I realize this is about what normal people consider art, but axiomatic set theory has a simple and elegant beauty more people should know.
Ben Elton. This multi-talented guy started in standup comedy, then hit is stride as a writer. He did Fry & Laurie’s Blackadder TV series, the lyrics to Andrew Lloyd Webber’s wonderful show The Beautiful Game, and a series of books that are fine reading.
I’m one of about a dozen peole in the States that have heard of him. And I wish he’d do a show with Elton John.
Richard Farina. From tart to finish, his short life was one of the coolest imaginable.
The wind chamber music of Mozart, Richard Strauss, Gounod and other classical composers.
Most people know band or orchestral music. The wind music I am recommending is usually for 8 to 12 musicians (2 flutes, 2 oboes, 2 clarinets, 2 bassoons and up to 4 horns).
Why is it good? It’s music written by the best composers that demonstrates the best featurs of their era. The individual parts might be flashy or technically difficult but what stands above all is the composer’s utter understanding of music.
The problem is that most instrumentalists want to play in a large group or the audience thinks that only a large group can be worth hearing. I’ve directed a couple of concerts dedicated to smaller ensembles and everyone (those on stage and the audience) enjoys the music.
Not at The Big Board. Beer prices fluctuate in real time with an algorithm that takes into account a bunch of variables. The more folks drinking a given beer, the further down its price drops.
Never been there, but the idea is cool.
I love Shaenon Garrity. When my family went to San Francisco, I insisted we go to the Cartoon Art Museum since she works there. I found a signed copy of one of the Narbonic volumes, and bought the two Skin Horse volumes. (My mom had already bought me two or three volumes of Narbonic and saved the wrapper with gerbils on it. Yay!)
Heck no it isn’t. It’s about anything you like. I am inclusive. 
All sorts of comic-booky goodness in a low-budget, light hearted, pop culture filled tv show.
This! Sadly, too short a run for a show, but this one is fantastic (and pretty much what I came here to recommend!)
Oh, boy! No more going through iTunes finding the songs that she’s not on (or the songs where she isn’t over-the-top operatic). I like the band, but I don’t like her vocal style. Now that she’s gone, I’m going back to look for new Nightwish music.
Sandy Denny - another one who died too young. My favorite singer, by far.
Blind Melon
Off to post in the "On Album X, Songs Y and Z get the most play/love, but the best song is clearly… " thread
Tom Paxton. Everybody knows some of his songs, but he is one of the best singer/songwriters going. Paxton writes amazing love songs(I Give You The Morning), political satire songs(Talking Vietname Pot Luck Blues), traditional folk songs(Rambling Boy), tribute songs(Phil), and children’s songs (The Marvelous Toy).I consider him a musical genius.
