Yes, that's definitely planned over the longer term, but the community is too small to support highly-specific groups for now. Various other "reddit clones" have made the mistake of allowing users to create communities immediately, and they ended up with thousands of inactive, abandoned ones. Even reddit itself didn't support subreddit creation for over 3 years. It takes a long time to have a userbase large enough for it to work. In the meantime, Tildes has a pretty flexible tagging system to help categorize topics, and tags can transition into formal groups quite nicely.
