What are the advantages Ethereum has over Bitcoin, except faster transactions?
Bigger than that is the tone with which the Bitcoin communicates. There's that prominent Bitcoin enthusiast who likes to cuss and scream and demonize perceived opponents on Twitter. There's another one (maybe the same guy?) who moderates with a vengeful bias on Reddit. That kind of shit-throwing is anathema to a large company.
Also due to some being unhappy with the moderation of /r/bitcoin there's a separate community called /r/btc. Then again, there are many communities on Reddit that have split up due to disagreements about moderation, such as for example /r/meirl vs the previously vastly more popular /r/me_irl [1]. (The latter of these still has about 3x the amount of subscribers though, but /r/me_irl has grown to become large indeed.)

Yes. The whitepaper lists many potential applications [0]. Some interesting ones today include issuing tokens for crowdsales ("ICO"s), gambling applications (FunFair), distributed computing (Golem), peer-to-peer payments and distributed apps (Status). There are many more that I am not familiar with.
>any idea what % of transactions utilize this today?
https://etherscan.io/accounts/c lists all smart contracts along with the amount of ETH they hold and the number of transactions that have called them. This doesn't completely answer your question, sorry.

Genrally:
- Bitcoin is a store of value token with the goal of becoming a decentralized reserve currency.
- Ethereum is a smart contracts token with the goal of turning all business operations into programmatic traceable transactions.
But Solidity is the flagship language.
Serpent is outdated; Viper is an up-and-coming replacement.
Solidity: strong static typing, class-based, all numbers are integers.
Javascript: weak dynamic typing, prototype-based, all numbers are floats.
