It's simply additional information. As others have said, you don't need to read them to appreciate the show, but they're not spoilery either.

And of course, the main problem is that "Heroes" is intended to be consumed in two media at once ... which is a little different than what happens with online materials for most TV shows. You don't lose much if you don't read the comic, but it's not the complete picture of the story, either.

Want an original \"Isaaz Mendes\"? The Heroes artwork is up for sale: [link]

Hmmm... not exactly originals:

Each auction will feature two full-size autographed limited editions prints and drawings of artwork used in the show, which includes \"Exploding Man,\" \"Eclipse,\" \"Claire on the Stairs\" and \"Hiro and T-Rex.\"

Also:

The first auction will start at 6 p.m. PAC on March 26 and close at 12 a.m. PAC on March 28. The second will be held at the same times but from April 2 to April 4.

I assume PAC is Pacific time? How annoying to end an auction at 3am on the East Coast!

I couldn't really spend too much time on that page, since the first user comment called Greg Grunberg a hypocrite for supporting a charity dedicated to epilepsy.

Yeah, that was stupid on so many levels.

Apparently you should only raise money for causes that you know nothing about and don't affect anyone you know.

I was sitting here thinking, Greg Grunberg is secretly in favor of epilepsy! He really really thinks everyone should have the tonic-clonic experience!!

...I think somebody needs to be beaten with a dictionary, to say nothing to the basic nastiness of it.

Yes. Otherwise, it's selfish.
