From the name, I would have guessed that it was about lampshading the Running Joke. Which would be Playing With a trope, not a separate trope.
The description seems to be "Nothing But Running Jokes", which is simply But More.
Some of the examples are definitely in complainy territory, though those may be simply misuse (e.g. the examples that say, "the sequel rehashes the jokes in the original", which has nothing to do with what's been described).
+1 to merge.
Actually, it seems to be intended to be more meta than Running Gag.
A Running Gag is a joke that is repeated or revisited a number of times.
A Recurring Joke Joke is a joke about the joke repeating a number of times.
That would be the lampshading I mentioned earlier, but neither the description nor the examples meet that definition, even if it did count as more than Playing with a Trope.
Maybe it originally started as Lampshading A Running Joke By Joking About It, but if so, it's been mutated beyond recognition. We could check the Wayback Machine, but I don't think it would change my opinion either way.
No, it isn't. It might sound like it should be, but it's about recurring comedy sketches based on a single running gag.
It didn't - I saw the YKTTW, and people were questioning its tropeworthiness even then, but it still got launched.
