I’m not sure where this spammy-feeling emailer read on this blog (ever) about my love of social media or toys (not of the belt-fed or Cuba leaf varieties).
It is so nice to have this chance to enjoy reading your blog:

Waiting for your positive reply.
I’m certainly not opposed to the Rube Cube, being a solid Gen Xer. However, the direction to post on the anti-socials threw this one into the category of things I’m opposed to and, thus, won’t participate in. There was also the spam factor. This isn’t the first of these kinds of requests either.
For future reference, here are my rates for unsolicited “collaboration,” subject to change per my whims, of course:
Things that REALLY interest me as requested by people I know: $1 per word, paid upfront;
Things that REALLY interest me, solicited by strangers: $10 per word, paid upfront;
Things that do not really interest me but which I do not find objectionable, as requested by people I know: $10 per word, upfront;
Things that do not really interest me but which I do not find objectionable, from strangers: $100 per word, upfront;
Anything else: Delete.
