Was happy to slate the St Regis Doha - I even had the GM post a comment!

However, you need to differentiate between bad things that happen to you and bad things that could happen to anyone. If a hotel loses your bag or forgets a wake up call that is not necessarily a reason to slate it in front of thousands of people, esp as peoples livelihoods are at stake.
On the other hand, if the building causes a shadow over the pool for much of the day or all the signs are falling down or views are not as advertises then you have legitimate complaints.
