It's correct for the 140 projects that I examined, which is all that I claimed. Check them for yourself. The number of projects that constitutes a reasonable sample of the "popular" projects (by whatever ranking) is a bit of a judgement call, but twenty seems very small to me. Every project in my list of 140 is well known, so I think it's a more representative sample. What do you see if you examine the top 140 projects according to whatever ranking you use for Central? > All the popular stuff is in Maven Central and > again, 94% is a huge number, saying it doesn't cover much is just > inaccurate. Nearly everything in Central is not popular. That 94% of all projects have a given property does not imply that 94% of the popular projects have that property. - Mark
