Dilly, I think that's a fab meme!
I am beginning to realise that, when it comes to blogging, there are reasons people do it that are financial - the more hits they have, the more cash they can get from doing reviews and having ads etc. (as I understand it).
IMHO, hits from Memes are not necessarily people who like your blog, though.
For instance, I want to drive traffic to my blog, but because of my reason for blogging, it is vital that the traffic is not meaningless traffic - it has to be people who are coming, and coming back again, to read the content.
Coming just because they're doing a meme thing would mean nothing to my blog - except that it might make people more aware of the blog. Personally, I'd rather have people coming to my blog through genuine recommendations, word of mouth (keyboard?) and from worthwhile comments I've put on other blogs i.e. ppl like what I have to say IYSWIM.
If I had a Mummyblog, or was blogging for to make money, I'd probably take part in a few for fun, but memes with strict rules the breaking of which triggers a telling off are, IMO, a little bit frustrating.
