Create user friendly "default" view for a Network (with no channels)

[bnvk]

As @jdittrich brought up in #12 what about when a user is connected to a network but no channels... how do we make this intuitive? A few ideas I have for this right now are:

• A semi-curated list of Channels that show "rich" item metadata (Title, Description, Image, URL)
• A search box with auto suggested channels

I'm sure there's more creative directions. I'd love to see (or will have to make) some wireframes exploring things.

As already mentioned in #4 we could make use of the fact that already visited channels could be saved in some kind of history and/or that a user might have "bookmarked" or "stared" channels that are visited frequently.
