This is the sort of thing where you can see that Marge and Dave from a couple streets over are going out to dinner Saturday and it's a chance to join in.
Given the way physical communities just aren't communities these days, this sort of site is a chance to reverse that.
Who do you think is on facebook and twitter anyway?
For example, a couple weeks ago I learned that Marcy Playground had released a new CD and was touring. I was bumbed I missed their show simply because I didn't know about it.
Now, if Marcy Playground was on Plancast I could've just subscribed to their upcoming feed and easily have seen where they were going to be and when they were going to be there.
Now, how awesome would it be if all your favorite bands were on Plancast? You could create a feed of just bands you liked and have their tour schedules come to you.
But let's not stop at bands, what about your favorite clubs or restaurants? You could create a custom upcoming feed of only the places you want to go.
Give Plancast a chance and you might just grow to love it.
But that's probably just me. I have never seen the allure of the "social" internet that puts ever facet of your life on line. It seems to be to be the height of arrogance to think that anyone really cares about where you are going to dinner on Thursday night.
Personally, I think that people will begin backing away from these types of start ups and will become less inclined to reveal anything about themselves. It's just too much.
2. People like to make stuff for themselves and their friends.
There are also people who, when they think "I want to go out to dinner on Thursday.", follow it up with "Naturally, I will bring my husband and children." These people do not have an endless stream of Silicon Valley companies trying to satisfy their every whim. That is a pity, or opportunity, depending on how you look at it.
