One small bit of feedback:
I'm guessing that "Email autoresponder", "Sync to phone", and "Add by forwarding email" are not available on the free plan as they appear to be struck out (likewise with "Add by forwarding email" on the standard plan) - but I had to look very closely to notice this.
You might want to redesign the comparison tables to make this more obvious.
It's a little hard to answer that question, seeing as you've already told me what it does. You're better asking this question of people that have no prior knowledge of the system.
No, but I'm happily employed - and should that change, I'd be aiming to avoid recruiters together.
