The Penscratch theme does supports italics, its creator uses it to differentiate links on her blog - some links, not all though.
The "Follow" widget requires an email address. I prefer RSS links, like the old Making epub happen blog had. I do all I can to keep my mailboxes free of notifications. Seems to me that the social media moguls, and the politicians who benefit from their largesse, are doing all they can to kill RSS.
