fix some sentences

  There was discussion on handing big graphs in the system, ones where the graph itself is
very large. Someone need's to take Paolo's PageRank-over-MapReduce code and test it on bigger
data sets.
  
- There was a good point on what is "efficient" in this world: If you can do it in O(n) on
MR, and there is no single computer in the world that can work on a graph of that scale, then
it's efficient.

- The key point here being that yes, something done as a chain of MR jobs on a Hadoop cluster
may seem an inefficient approach, but if there is no other way to store that much data, or
run through it, then graph people will be happy.
