@wilkie Seems like for already_posted? (and just ```do_not_repeat_yourself``` prior to this change) you'd actually have to look at all prior statuses and compare the text?

In it's current from, whether you leave ```already_posted?``` or do as wikie suggests and go with:

```ruby
def do_not_repeat_yourself
if feed.last_update && feed.last_update.id != id && feed.last_update.text == text && feed.last_update.author.id == author.id
errors.add(:text, "You already posted this update.")
```

You're still only really checking the previous update.
