AnonyMint knows his shit!

Agree, he is very biased and hard to deal with, but his posts are well worth reading.

please stop preaching the security of a chained algo. chained algos are only as strong as their weakest link so if one of the algost piled on top of eachother in x11 breaks the whole chain breaks.

how come? I thought it was the opposite, since if you can break say the first algo you still have 10 rounds of hashing to do so it's not a huge speed up anyway

Well, that's correct if 'breaking' means finding a way to almost instantly calculate hash value. But imagine that a way to instantly find a collision is found. Bitcoin code (on which almost all altcoin wallets are based) prevents duplicate block hashes, but one can 'borrow' valid block hash from another blockchain with the same PoW algorithm and reuse it. Another question is where and how inject arbitrary bits into block header, there is only 32 bit of nonce and something like 14 low bits of time value, so this attack is rather theoretical for now. Quick conclusions - the first hash in chain should be the strongest one, high difficulty blockchain could damage its weaker siblings with the same algorithm.

Point is, if there's less heat, then your card isn't working as hard as it can. Basic science.

Point is, if there's less heat, then something surprising is going to happen. Basic common sense. Watch the Groestlcoin

8. does having 11 algos cause high orphan rates

I think no, as long as PoW hash is not used to calculate Merkle root, but even this would be almost insignificant. And most altcoins use old good double SHA-256 for transaction hashes, IIRC.
Orphan rate is an excellent topic, I'd be glad to see a good discussion about it, though I have almost nothing to contribute to it.

X11 algo has a planned transition to ASIC miners.

Very interesting! Could you give a link to discussion?

what did you mean when you said it could create more collisions?
