1. If you want to friend me, for whatever reason, go for it.
2. I may or may not friend you back for any number of reasons. If I don't friend you back, it could be one of these reasons:
a. I have no idea who you are.
b. We don't appear to have many (or any) interests in common.
c. I meant to and forgot.
3. People use the friending feature loads of different ways with all sorts of different sets of assumptions about what it means to "friend" someone. Here is my only assumption about friending: there is some interest in reading what the person writes on their LJ/IJ/DW with some regularity, which may or may not have anything to do with being friends in the more usual sense of the word. Actual friendship develops and becomes evident through interacting on each other's journals or in communities/asylums or even (gasp) offline.
4. This is not a strictly fandom journal. I've been on LJ longer than I've been in fandom, and while the opposite is true for IJ and Dw, since I crosspost almost everything to both of them, they both have the same mix of topics including fandom stuff, school stuff, relgious stuff, political stuff, dance-related stuff, and just general RL stuff. The balance of what gets the most screen space can shift without warning. Which fandom has grabbed center stage similarly shifts without warning, often even to me.
5. I don't flock much. When I do, though, I tend to filter it, because my flist is so eclectic. I tend to make it clear in the subject line what filter I'm using. If you find yourself reading posts that are filtered to a particular set of interests you're uninterested in or uncomfortable with, let me know and I'll take you off. That said, back to the start of this point: I don't flock much.
Also, this is not a comment to be added post. In fact, I'm turning comments off, because it seems whatever my "top post" is inevitably gets tons of spam comments, frequently in languages I don't speak.
