RE: First steps into Decentraland
I apologize that I missed your comment. Reddit has a small Decentraland community, which may have some useful information (although much of the discussion revolves around MANA prices). Several of the Districts have started their own Slack accounts. In my opinion, it's been a bit quiet the past few weeks (since the auction ended). The Decentraland team is working to create a Mana wallet that could be used for trading land (via Ethereum smart contracts, I believe). I'd recommend following Decentraland on twitter, also, for up-to-date info.
I think that for anyone interested in virtual reality, there is incredible buzz and potential around this project. Also, you may want to check out this past weekend's "Rare Digital Art Festival", which was held in NYC. There is just an incredible amount of potential uses for Decentraland, including virtual art galleries.
I need to post more often! Thanks for your interest, this is good motivation for me to get writing again. I'm currently teaching myself programming, with the goal of learning virtual reality development over the coming year. Take care!
