Tipadvisor: from pretty useless rating to useful tagging and filtering

What is Tripadvisor?
A website where you put 3, 4, 5 stars to a place and write a little story.
Tripadvisor is cool to rate overall popularity of places but it's crap for all the rest.
Why?
Because they miss tags, the miss filters!!! They miss structured data. They focused on unstructured data with millions of stories. Unfortunately, transforming unstructured data into structured inputs is a headache.

You want the top 5 Italian restaurants in Paris? You got it in Tripadvisor and most of the time, it's good recommandations. Top restaurants deserve it.

For all the rest, look...

Want the top 5 Italian restaurants in the Paris's 15th district? Well, without "district" tag, no way.
Want the top 5 Italian restaurants in Paris with Veggie option? Well, you can type Ctrl F to find the word veggie in comments... except that comments are cropped... never mind, ok no way. The tag "veggie" is missing.
Want the top 5 Italian restaurants in Paris with a terrace? Well, we don't really keep track of which restaurant has terraces or not. We miss this tag...
Want the top 5 Italian restaurant in the Champs-Elysées? Well the only way we handle location is a map and radius distance, we can't use the street as tags and filters.
Want the top 5 Italian restaurants in Paris which can deliver food to you? Well...  no delivery tag, sorry...
Want the top 5 Italian restaurant who take credit card? Well, call them... we don't tag payment methods.
Want the best pizza 4 cheese in Paris? Well we don't really keep track of what people eat and tag dishes...

BUT things are changing!!! Tripadvisor finally got it and now asks its enormous community to put 4 or 5 star and a story nobody cares... and to tag restaurants: kind of cuisine, delivery or not, terrace or not, best dishes, service, etc.
Look:

What a move.
I expected that for years. Well done guys.
You're late but you're still ahead of the others!
