So I wanted to say that I really love some web service, (I could pretty much say this about stack exchange too!) and I wanted to keep the power of my words, but I have a bad habit of using f-word in english more than I want, since English is not my native tongue and it makes it easier, when you lack rich vocabulary. I heard that usage of f word has a strong connotation and is generally perceived badly. I am not sure how to replace such an expression. There is the "God, I love something something", but I would also like to avoid using the word "God".
There surely are common ways to express such a thing, but I cannot come up with anything. Would you suggest some ways, please?
