This gets much more attention than it should in my opinion. Its another micro nation that within few weeks no one will remember about. Besides stamps collectors and non-recognized passport holders.
Au contraire, I've been casually following "micro nations" for decades, and attempts are often long remembered. This one is notable as it involves actual viable land (in contrast with artificial or new/fluke natural dry surfaces), which the surrounding countries just plain don't want. It's not just a rock or platform with a flag on it.
Indeed, with a little persistence and some capital this could turn into an interesting project. Like Bir Tawil, it's a piece of land which is not just unclaimed, but in fact definitively disclaimed by the adjacent nations - but instead of being a barren patch of North African desert miles from nowhere, it's a pretty little patch of forestland on a major river in central Europe. Nor does it seem likely that Serbia and Croatia will be settling their differences over the border any time soon.
Some are just notable crackpots, some take advantage of geographic changes or artificial structures (Sealand the most famous), some are whims tolerated by controlling sovereignties, some are violently overthrown, some are long-respected special cases (Vatican), some are genuine attempts that failed (Oceania).
