We’ve broadly scoped dyalogues to mean any sort of back-and-forth exchange between exactly two people.

That’s pretty broad. We know. At least at the beginning, we’re launching with two formats:

• debates
• dual reviews (two people review something together; think Siskel & Ebert, or Ebert & Roeper, I guess)

There are two other formats we’ll launch down the road:

• interviews (one user interviews another)
• multi-step advice (think Dear Abby or Ann Landers, except you can ask follow-up questions)

There are some differences in the UI for each of these formats, but primarily the formats will be grouped together, so if you’re an interview fanatic, you can read interview after interview in the same section on the site. Or if you want to read what everyone has to say about the new Blackberry Pearl, then you should be able to see all of those reviews collated in the same section of the site.

There might be other formats that we’ll test down the road, as well. But these 4 are those that are on our current roadmap.
