More specifically, the cashtag "$PATH" leads to a search results page with any mention of the term "$PATH" (which is useful for searching for finding tweets with stock symbols). This search results page also shows any highly relevant users, which is why @Path shows up. Searching for $MSFT will show the account for @microsoft, for example.
