Hi! Welcome to the english language, is this your first week?

I looked at the page you linked and I realize there are people like those described there. That being said:

I think some people (at least one :) use "I feel" to express a notion that is too intuitive for a concrete statement like "I think".

I feel like that's what MBCook intended. ;)

Wow, that page is full of garbage.

Use http://en.wikipedia.org/wiki/I-message instead.
