I totally agree with you. What is the lesson here ? You need indexes to speed up queries in any structured data storage. Uh, great but I am worried about the glipho backend then. All this to get a bit of advertising.

I partially agree,

I don't see how one would not find this obvious after reading the mongo docs which explicitly say

> Indexes enhance query performance, often dramatically ...

I think the point here is that many people don't realise indexes matter so much in MongoDB. Their documentation doesn't go out the way to push indexes as a must. That coupled with the ease at which you can just start using it compared to say, MySQL, means that people find it interesting.

I will point out that while I wrote this, it was more to try and ensure other people don't make the same mistakes.

Exactly,the article doesn't really have anything much to say. Overhyped,headlines all over again.
