Popularity issue persisting after 0.5 release

Here are some numbers:

• Over the last week, we had about 500 active players (unique IPs seen per 24h interval), online and offline play.
  
• Furthermore, we had on average 7.1 players on online servers at any given time.
  
• We had 11.4 downloads per hour, makes 1915 downloads total during that week.
  
• We had 5.4 new players per hour, makes 907 new players total during that week.
  
• On average, 17.6 unique users are online on our main website.
  
• On average, 30.8 unique users are online on our forum.
  

This leads to the observations:

• A player on average plays this game for 20.5 minutes per day online, which is neither surprisingly low nor high! Note that offline players (botmatches) count as zero minutes for this number, so this is likely a mix of many offline players (and menu clickers...) and of about 40min to 2 hours online players.
  
• Less than half of the downloaders run the game even once! But this may be normal loss, but may need looking into.
  
• Apparently, many follow the forum daily, but don't play the game daily
  
• Less than 2000 downloads per week. We REALLY should be able to do better than that. Near release time we had 1096 downloads on a single day.
  

Basically, from this I can already conclude that it's not the game which is wrong. It is that not enough people try it. So how do we get the word out to the "proper" channels?
