What are the ways I can contribute to Ethereum?

Question

I'd like to know more about how to contribute, both on a technical and non technical perspective

Answer 1

you could participate in / contribute to the homestead documentation initiative see the scoping out discussion here

you could contribute both tech and non tech answers / commentary in the Ethereum Forum

You could run a wallet, buy a few Ethers for it & provide technical or empirical feedback (or both) on that experience here

Answer 2

You can

1. Run a node
2. Mine the Blockchain
3. Be an evangelist

And there are plenty other ways, like provide support in forums, and most probably buy ethereum (ETH)
