EVE Blog Banter 39 poses an interesting question: what does "home" mean in EVE Online? That's paraphrased, obviously: you can read the full question and see other entries here.
My answer: home is where you had all your shit for the longest period. Simple and un-romantic, I know. But in EVE, there's not a whole lot else to define home with. You might define home as "the place where my POSes are". But they're really your corp's POSes, so that's more the corp's home than yours.
If you hang around a place long enough, it grows on you. You get to know it. Make a few bookmarks. Anchor a few cans. Accumulate a metric shit ton of mostly useless gear that you never get around to selling. That's what makes it home. But I think...there should be a way to really make it home, rather than just a corp POS or a station that happens to be friendly right now - or NPC. I'll discuss that here, I guess, since I don't really have much else to say on the topic of "what is home?". It's thought-inspiring, but there's not much you can say about the actual topic.
WARNING: rambling probably-should-be-in-F&I bit ahead. TL;DR: make mini-POSes.
A true home should let you customize it, let you park in it, let you build it as you go. Let you make it yours. You can do that with POSes right now...but unless you're fairly rich, run a one-man corp, and have a few alts, POSes are the domain of the people you work for. They're COSes, not POSes. But what if they were smaller?
I like the idea of a "proper" POS. A small station, anchored in deep space, with low maintenance, modularity, and room for customization. Depending on your income and how long you've had it, it could grow from a few storage hangars...

|Hive of scum and villainy|
In closing, home in EVE right now is something that you can easily designate, but there need to be more ways to make it truly yours. Mini-POSes could do that. Maybe there are other ways. But we need to have something better than this.
