As a shrine creep, I've always enjoyed meta-analysis over the little details. It doesn't necessarily have to be personal, although that's what I most like, and often what I feel like longer form essays end up being about is the person, even if they don't use 'I' statements. You see a lot more about how they think and what they think is worth notice and how they connect things -- I'm there for the fan more than I am for the subject. I suppose fansites by their very nature are personal (because they're predicated on a creator admitting they're a fan of something), but I feel like the deeper commentary gives me more as a reader than the facts. If I antecedently cared about the shrine's subject, and wanted fact-y information, most of the sources for that are not on fansites. (But then, maybe this is coming from my weakness: I don't hold on to details for long.) But I can care about another person's passionate interest, even if I don't know the person before I read their site, just because what makes something interesting can be shared the more they say about why they think it's interesting. And often that leads me to interests I wouldn't have tried, or shapes how I experience that subject going forward. And then I have two things: I have this new interest or experience of a character or a show; and I have this relationship with the writer, even if they don't know about it, even if I ultimately disagree.
... and obviously, some of this is because I can TLDR too.
I always appreciate someone who can be concise, and I imagine some people can do that after they draft a site a few times, or if they've had a site for years and their relationship to the subject or to shrining changes, they can cut out content. (Or perhaps they just have the gift of less gab!) But often when I write, it's often as much about trying to figure out why I feel the way I feel, sometimes even just about how I feel, and I find it hard to eliminate the pieces of the writing that describe the order of discovery. I get a lot of joy from coming back to something I wrote that I no longer remember, and remembering my way back to how I felt when I wrote it. And I guess, since I don't expect many people to visit anything I make, some of the justification for it has to be selfish, since it's not likely I'll give much to anyone else. As you read above, that's not how I've felt about most of the shrines I've encountered because I still remember the long gone freaking Save the Queen tribute to Quistis, but I'm also aware that there are so many more I haven't read than shrines I have read, and that means that there's going to be a lot of people who don't read what I do, and fewer still who care about it. So what makes it worth while if it's not really going to be for others? For me, it's trying to show my self why I care about it, either my present self through writing to discover my feelings, or my future self, when I eventually revisit my work. Obviously I'm a newb, so we'll see how this pays out, but when I did written role play, finding old work was a surprise, and always revealing. Hoping shrining will be the same. The more 'in depth' stuff I keep, the more I'll be able to remember, I hope.
