This has potential. I can see how it could differ from Services: it would usually have one or two people per thread offering a small job (not a recurring service) on a case-by-case basis.
Yes. And it could be big jobs too.
I'd prefer to define "jobs" as some sort of skilled work that requires a worker's time such that (a) writing code would count as a "job", but (b) renting your signature space would not. Basically, I'm trying to improve the SNR.
There is enormous potential for bitcoin to create a sort of "micro jobs" market. Imagine a future where many people just wake up, say, "hmm, I want to make 0.1 BTC today," view a pool of posted jobs, find one that they can do, submit the work and receive payment.
If this process become highly efficient over time, I bet I could contract out over 50% of all my engineering projects on a "piece by piece" basis to people all over the world. If this became more commonly used, it could greatly increase the GDP of the bitcoin economy, while giving workers greater geographic mobility.
However, we would need to make sure there would be enough people participating in it before it could get its own section.
I think the opposite is true. We could make the new section with clear rules and expectations so that it is useful to the community. If we make it useful, then I expect more people to start using slowly over time.
