In short - a straightforward reading of the 2 outside projects'
write-ups is likely to lead to some problems. We should try to thrash
out how to avoid these problems.

Lately in my communications with people I try to emphasize that Wikipedia isn't just an online encyclopedia, but a social network. It has developed many characteristics similar to other social networks.

I know I'm in the minority, but I strongly feel that anyone editing Wikipedia should create a username if only so that they can be communicated with.

If they don't want to create a username, then instead of jumping into edit, they should probably find who is the creator and/or recent editors of the article to which they want to add links and talk with them. This will hopefully forestall the assumption that they're spammers/vandals. It might be also the beginning of a dialogue that's useful to both Wikipedia and the institution that wants the links.
