Offered: Room to rent in London Fields 400pcm

hmm - Vinz, went for myriad as a noun eh? Some might have been tempted with the more usual adjective and said "the link gives me myriad choices" - but somehow this is rendered clumsy by the repetition of "m". In using the noun you use the indefinite article as a break between the two "ms" - and then somehow you manage to lend the whole sentence a more pleasing meter by the necessity of the "of".

Nice to know someone else is thinking about these things.

My thinking exactly.
