I only jump back into minecraft and the rev a few weeks ago, but early on, I found it quite confusing to find how to get to the spawn nether portal. There is /place and all, but the fact that the spawn building only had 1 marked south exit, and 2 unmarked north exits makes it a little challenging to find how to get to the portal, and ended up with me eventually discovering you had to walk all the way around the building. In particular as well if a spawn-based attraction, such as the public gardens, is created, it would be beneficial to attempt to lead people there somewhat if they take a bit of time to read all the signs.
tl;dr: if there are key interests around spawn, make sure they are accessible from within spawn or there are adequate directions to get there.
