If I stop checking FT due to travel, I stop receiving emails.

I only ever receive 1 email per thread when there's a new post.... which is less than ideal. If there's a post that's nonsensical, I can read it in the email and don't need to visit the site. However, until I do (for that thread or another), I don't receive any email for that thread for any other new posts.

It's not ideal, but from an ads/page views/visits standpoint, I understand why.
