please discuss the reason why why text or ntext is not recomended for use in sql server. thanks
They are deprecated, won't work in future versions and working with them is a pain compared to the replacement datatypes (varchar(max) and nvarchar(max)) as most string functions don't work with them.

How to find vulnerable sites, where one can login using '0'or'0'='0' and such other combinations ?
I believe you are asking the question with reference to to SQL injection. If the login control is using a query based on string concatenation then chances are that this will succeed in logging in.
It should be: ' or '0'='0

This question is totally unacceptable and will be closed but...
Has SQL Fiddle been amalgameted into Stack Exchange? For example in HERE
Also - THIS is crazy - Am I correct in saying this is sql that is querying SO itself?
(... can't wait to play.)
First, such questions should rather be in meta.
Second, the data explorer has been around for some time now; it's not about executing arbitrary SQL code but for queries against the SO database.
See meta for more questions around the data explorer: https://meta.stackexchange.com/questions/tagged/data-explorer
