The I2P private beta didn't have enough activity during the beta and has been closed recently. This most likely to happen again.
I suggest to join the forces into Darknet proposal (previous follow up of Deep Web proposal). This way we'll avoid the same mistake of lack of activity by expanding the topic for other anonymous networks as well, so the site can be more interesting.
Otherwise it doesn't make sense to have separate dedicated sites for I2P, Freenet, and other network invented in the future (e.g. Hornet, etc.). I believe these kind of decentralized networks have a lot in common.
