Subject Re: Lowering the barrier

The main problem is that we have very huge issues: I/O, graph, multitask.
We need more minor bugfixes or a better splitting of issues.
And like you already said, a far more better documentation. Not in the Wiki
and in some PDF, but on the website.

In my opinion people should already have some experience with Hadoop, like
starting HDFS for example.
But this is not the case for everyone, so we should add a tutorial for that

Thanks for the good ideas ;)
