That's a great idea. It just seems that every problem I run into has already been solved.

Yes, it is. But I can't recognise my own problems anymore, because I've become so good at solving them myself.

If you no longer have any more problems at all, sounds like you are either the next generation of humankind or you aren't pushing things enough. I suspect it's the latter.

I'm talking about practical/technical problems of course.

Now that's just pretentious and not true.

Why not use Neat for your grid and Foundation for typography?

Honestly, I've been thinking about it. Have not tried it out that way yet. One step at a time. Step one was upgrading from 3 to 4 and doing some semantic cleanup (no more grid classes anywhere).

EveryMe is something different. They add a social feature to your contacts. My idea is about always having the most up to date personal contact information.

They're just ideas floating around in my head. I want to make sure I'm not reinventing the weel.

if you start posting at G+, feel free to add me, will be glad to share thoughts.

I'm actually thinking about a celebrity/gossip niche. It would be fun to just read articles and watch pictures/videos of a certain celebrity, without visiting multiple websites. I just don't have a clue how an aggregator is build. Do I have to build a crawler or can I just use the RSS feeds of certain websites?

The sites I mentioned just aggregate the RSS feeds from other sites.

Love it!

I'm only studying to get a degree. Without a degree, it's hard to find a proper job in Belgium. CS has interested me since I was a teenager, that's why I choose it.

You're absolutely right. Sometimes I let myself be carried away by the fears of others.

Really appreciate your input, but your statement about my idea is rather brusque. You don't have a clue what my idea is about. It is possible to take a leave of absence at my university, which I'm considering. I might even go to night school getting a bachelor's degree while working on my startup during the day.

Sorry, that was a poor choice of words, and I apologize. But I still think it's a bad idea, if only because you're going up against multiple billion dollar companies. You're essentially a novice climber who wants his first climb to be Everest.

Business isn't easy; you'll need every advantage you can get. My advice (and what I'm personally doing, after being in almost the same situation as you) is to build a smaller business first, specifically something that does not require a network effect to be useful. In other words, a product that is useful to a single customer without any other users. See stuff by 37signals and most SaaSs in general for examples.

The end point is really that business is hard, and it's infinitely harder when you go after something huge like eBay on your first try. That's not being bold, it's being foolish.

Why not build something smaller to learn more about business, make a good bit of money from that, and then take on eBay? It is quite a bit easier to build a 100k/year company than a 100million/year company. Plus, you'll have money to bootstrap your company.
