webdev, nostalgia, and a preview

So now that I'm an entry-level web developer (read: finally started building my own servers/SQL databases/writing php/finally understanding what Dreamweaver ACTUALLY does ha) I've started to recognize the potential of my new-found internet superpowers. (That's actually a bit inaccurate; understanding the potential of what we can really do with a few basic tools is what drove me to pick them up in the first place and I highly recommend it. I started at xampp. not that it's necessary but it's nice and packaged.).

I promise I'll use my powers for good.

What I've chosen to begin with is some kind of repository/tool/application that will categorize/visualize/organize submitted entries of things that we consider meaningful, nostalgic and generally just miss. Since the prompt will be something as simple as "I miss: _____ " these things can be profound or simple, and I'm looking forward to seeing what responses I can end up with because they are sure to be fascinating.

The question I'm working on now is: "what's the best way to visualize a list of memories and nostalgic things"? My initial thought is to think of ways to apply tags and categories. Probably some kind of BuzzFeed-like set of pre-determined tags, as well as a quick prompt for the submitter to make up their own if they so desire. Those tags can be cross-referenced with each other for some interesting analysis. More thinking on that needed. Any thoughts?

Anyone want to do some beta-testing once I set up a domain and all? Let me know, you'll get an exclusive peek.

Or if you'd rather, here's a quick way to help: what's something you miss?
