The problem with getting some of the people on youtube who frequently popularize indie games to make videos about blockland is multi-faceted. Blockland does not really lend itself well to videos except for machinima and showing off already-made builds with nice pans and vfx, neither of which somebody who has just bought a blockland key is going to be capable of making for their youtube channel. Watching a person build with lego in a 15 minute video is not interesting for anyone but the person making it. The second part is that there's a lot of bits of blockland that we take for granted. I would imagine that, were someone like Tobuscus or Totalbiscuit or the Yogscast to boot up blockland and join a server, in all probability the impression made would be very poor. In the more likely scenario that they just booted up a single player game, they would get the vanilla blockland experience. What the person giving their impressions of the game would NOT KNOW, where they to do this is that a lot of blockland's problems and shortcomings are fixed in add-ons and the reason they aren't patched into the game is because add-ons are taken for granted in the community. Blockland is an OK game without add-ons, but I honestly think that it looks quite poor in comparison to a blockland with some brick packs, the smooth brick textures and a good colorset. I really am not sure that this is a barrier that can be circumvented and thus having someone external promote the game is pretty much out.
