Interesting. I suppose that must happen to me on Reddit. I'm middle aged and the vast majority of the posters on Reddit are teens to early 20s and it just seems like we cannot relate to each other at all. We just don't discuss issues the same way at all.
On Slashdot I have pretty good karma and rarely get downmodded, but on Reddit every single post I make gets downvoted. Every one. I kid you not. Often by as much as 10-15 points.
It may just be that I have a lot of enemies over there, but I think it is also a generational thing. When I post at some level I think it must feel to them like their parent or something and they have to downvote it.
What I find strange is that because every one of my posts is downvoted I just ignore it. It doesn't cause me to post less. I haven't found the negative moderation to have any real negative effect. I suppose it does mean that there are fewer people who can read what I write because I would guess that not everyone changes the default visibility preference to something more sensible as I do. I can still see posts that have been downvoted to like -30 or so. Since I still find posts at like -15 or -20 to have value it seems that unlike Slashdot, the moderation system over there just isn't effective. Well at least if its purpose was just to censor obvious trolls and spam. But then I don't find any serious discussions over there at all.
