Putting "fuck" in the domain name adds nothing and it makes me less likely to share links with some people who's sensibilities matter to me. My grandmother is one such person. She's one of the few people I'm close to that would really appreciate the functionality of this site, but it's just not the kind of domain name she'd be comfortable going to.
It's not that you're wrong, it's that being right wins you no prizes here.
You're being obtuse.
The taboo around certain words in certain contexts is a consensus that serves a purpose. You can use them and receive certain extra attention, but also lose other people to distraction.
Like others, I have no problem with using this myself, but wouldn't pass it on to a general audience. If I were to do so, I would signal that I am careless and casual with the use of the word 'fuck', when it is too important of a word to devalue so.
If the creator's goal is to limit adoption to a certain audience, the use of 'fuck' is a good idea. If they want wider adoption, it isn't. Both are valid choices.
Sure, and in this case, good riddance to them. Anyone who avoids sharing this app because of the word fuck has zero sense of humor and isn't the target audience. Anyone who critiques it for the word fuck, isn't the fucking target audience. There is nothing wrong with the word fuck in non fucking formal circumstances, even to a general audience. There are times not to use the word fuck; this isn't fucking one of them.

I'm with the OP, domains with foul language don't hit my sharing feeds and I'm not likely to make it a habit of frequenting the site.
While that may be true for you, my point is that I believe that to be a shortsighted view. It will almost certainly reduce your chances of finding some interesting material. Maybe the trade-off doesn't matter to you, and I certainly can appreciate that, but a trade-off is being made.
And it really doesn't matter if it is logical. It is reality and if you want users, you have to work the existing system.
Sorry if it sounds illogical to you, but you must accept people's sensitivity might be different from yours.
While nostalgic at this point, it seems like a waste of time to spend any effort on such a thing in retrospect.
Edit: Grammar and clarity.
There are plenty of uses of the f-word that I find funny, witty, or appropriate, but this is simply not one of them. (NSFW humor: http://justin.justnet.com.au/rudestuff/uses-of-the-word-fuck...)
It would be completely valid in this case to consider what they might think.
