I can't imagine WebM impacting 4chan anytime soon, it will probably reduce 4chan's load when(if) WebM takes off but I highly doubt more than a small fraction will choose WebM over a .gif in the immediate future.
WebM has caused longer animated content to be posted that wouldn't have been so possible as gifs (the limit is at 2 minutes iirc), so there will still be people posting large files.
Yes. It's very sad that /v/ has it in for Fish. I thoroughly enjoyed Fez, and IMO it's up there with some of the best.
He might be a bit of a dick, but so was Steve Jobs. Interesting how Jobs is reveared and yet Fish is despised—perhaps it has to do with the "maturity" of the respective "fan clubs".
The ending to the article is touching. In light of that what I am about to say is going to sound all the more heartless and I expect to get downvoted for it but I think that it has to be said:
If you really want to get things done, consider not having children (yet).
In my experience this applies to both men and women in demanding technical fields. You may argue that having children is worth it in spite of what it may do to your career but that's a different argument.
