The Tooth Fairy tie-in poses an interesting question. In the initial draft of this, djkaktus was worried that this was too similar to the Tooth Fairy. Apparently between that initial draft, and the final, the writer of the Tooth Fairy gave dj permission to tie it in. So my interesting question is this:
When you are writing a concept that has been done before (pretty well, IMO, btw, that was the first article that I felt I wanted Brain Bleach for), how do you deal with it. I feel that you have a few, no-win options:
1) Don't acknowledge the previous article, and suffer all the 'it's just like the previous article.'
2) Have a nod to the old article, such as 'links between this and SCP-xxxx are being researched,' and suffer the 'you're just trying to milk a previous article.'
3) Fully integrate the previous article into new one, and risk, well, the type of comments this has gotten.
While I constantly quote that 'anything can work IF you pull it off well enough,' I like how this pulled it off. The basic concept doesn't really on the Tooth Fairies, but it adds to the history of the piece, along with tying it in to previously established canon.
