Arunoda does make a lot of great contributions to the Meteor community. MongoDB oplog tailing was actually introduced by him earlier (http://meteorhacks.com/lets-scale-meteor.html). Although the core Meteor team probably had this on their radar, his implementation was the first publicly distributed, and he's one of the leading Meteor users pushing its use into production and reporting on how it goes.

Give the guy a break. He does a lot of great work and does his best with English (I believe he's based in Sri Lanka).

Well written piece actually. Perhaps you read something else.

I think this is one of the best articles out there and its very understandable on the issues when it comes to scaling meteor.

Really? I had no issues reading it and completely understood the content.

A new version was pushed part of the way through the day. Editing wasn't finished when it first went out.
