Standard Features: The checklist from hell

The industry term is "scope creep." The everyday human term is "a bunch of extra crap." One of the first few questions you answer when starting a web project is what are the core features. What's our site going to do for people? The simple answer you start with usually grows into a rambling monster of: instant personal messaging, event auto-recommendations, mobile video chat, holograms and real life status pokes.

At this stage of the web game, there is in fact a suite of features that set the standard. It's hard sometimes to step back and evaluate the difference between industry baseline and creeping requests.
I thought it might be good to create a list of the top basic features; things that won't differentiate you. But the right combination, plus nailing even JUST ONE of them, just might.

This is a check list NOT to be crossed off. Your job is to choose the subset. It's the right combination of basic features, for the right people, plus of course your totally awesome new twist.

*sigh* Now try and be choosy.

Course there are some newer features, that I'm sure will be standard by 2012, when Sarah Palin runs again. Ha!

• Alternate discover view mode
• Personalized recommendation, filtering
• Rich media meta indexing
• Organic data organization/clustering
• Comparative aggregation tools
• Mobile location check-in
• Location specific content

• Location independent conversations
• Automatic outside social integration

Barring the last two, I do actually have examples. These aren't empty predictions; I'm saying these things are to be standard in a few years. Their fringe now, not miracles. Here's what I mean: vimeo toys, digg labs, strands, youtube tagging, google gaudi-- sets-- inquotes-- trends, flickr draw searching, pandora, memetracker, powerset, chacha, etc.
