We mean the verb takes the dative, right? I thought case only refers to nouns.
We mean the verb requires a dative object which is a noun or pronoun in the dative case. If you look at the top of the lesson page in this dative lesson section, you will see the pronouns listed for the dative case as well as for the accusative and nominative, as well as info for "the" in dative case for the nouns.
"Ich liebe dich" has the same exact sentence structure as "ich danke dir". So why do we use "dich" with one and "dir" with the other? They mention dative verbs in this thread... so, is there like a list of verbs with which the dative is always used?
See here: http://german.about.com/library/verbs/blverb_dativ.htm Naturally, the list is not exhaustive.
Question: Is "ich danke dir" or even "danke dir" a common expresion in German, or do people usually just say Danke?
Yes, from experience I have heard people use 'danke dir' fairly commonly. It is colloquial, and not generally as common as simply 'danke' or 'danke schön,' but yes
Colloquially, this is often done. But strictly speaking you can't leave out the subject. So it's fine to use but I think duo shouldn't accept it as a correct solution and insist on a complete sentence.
I wrote, "I am thanking you" and was rebuffed. My ego is bruised. I know it is a trivial matter, but I feel this program is more limited in English than I am limited in my baby Deutsch.
It is correct (even though it isn't a sentence you probably wouldn't use very often ion English). You should report it if you haven't done so already.
'Dir' would be used when speaking with one person and 'euch' would be used when speaking to 2 or more people.
