If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
I have a similar aversion for similar reasons, and choose to, when possible, display symbolic representations of ideas/groups rather than specific words; group members or people familiar with the same ideas will recognize them, and others won't.
It would be nice if there were good abstract symbols for LessWrong, rationalism, and/or EA. I've gotten good results from symbols for smaller groups (ex. the fandom for the awesome yet moribund MYST series), and it seems useful.
I made a T-shirt with the Pioneer Plaque drawing, and always try to wear it when I'm expecting to meet new people. Those who don't know what it is will just ignore it, it is unobtrusive and would likely be considered pretty. Those who do recognize it always make a comment.
