Re: It's not infighting
'...now has double Apache's market share...'
If you read the full stats you linked to as opposed to cherry-picking one graph, it shows that Apache comfortably beats IIS in terms of actual use, and nginx is severely eating into the market share of both Apache and IIS. IIS actually shows a long downward trend in most of the graphs that isn't showing any signs of stopping. Take off the rose-tinted glasses and try scrolling down a bit.
