My Favorite Part of Twitter’s E-mail

Twitter’s e-mail was awesome.

Why?

1) I opened it.

2) I read through it.

3) It provoked my attention.

Twitter is so good. I can’t decide whether to even hold this against them.

Other questions that I’m wondering:

The Twitter team sent out an e-mail to Twitter’s users (Subject: “Update: Twitter Apps and You”) and posted a few updates about Twitter’s evolution on its official blog (e.g., The Evolving Ecosystem or A Better Twitter.)  Each presents information about Twitter’s growth and changes but uses slightly different language to communicate or emphasize certain points.  Does that make sense – should the same information be found in one place?  Or, even if the varied perspectives/distribution methods are valid, is cross-referencing appropriate?
