It seems to be the best way to get new ideas across to people. How would you describe them in a clearer way that as many people would understand?

Also, Glio looks like a copycat, so it is exactly Yelp for Brazil. That is what they are building, not just a form of explain their model.

Remember those times when people discussed how YC model was "cooler" than Rocket Internet model? Those times are gone.

I don't think that is an issue. The value in Yelp is largely in the reviews, the rest of how it works has been done plenty of times for plenty of different things.

Just like a groupon or stripe, the venue reviews space really needs boots on the ground and some local knowledge to work right, so there is a big opportunity for essentially a copycat model for that market (same as has happened for a long time in china).

Bringing these tried and tested ideas to places just catching up to the rest of the world with digital connectivity is probably going to be very lucrative over the next decade for people well positioned to do so.

It goes both ways. The names are so nonsensical that I had to stop and think about what each service they were referring to does. No idea what Yammer is, and I was so inundated by weird names that by the time I read Yelp it didn't even register.

I don't know. Maybe use some sort of journalistic tools.
