It's shocking but it's true. h2g2 site launched on 28 April, 1999 and so is ten years old today.

Since the most important element of this site is not its pixels or its software, but its incredible, unique Community, we'd like to wish you (us!) all Happy Birthday!

That very month, Douglas Adams announced his vision for the site, in which he managed to anticipate collaborative online encyclopedias:

I did have the inkling of an idea that a collaborative guide, one that was written and kept up to date by the people who used it, in real time, might be a neat idea.

and so-called 'Web 2.0 Principles':

We're gradually beginning to get some tiny, tiny inkling of how powerful a networked community sharing information really could become.

It was quite a prediction in a pre-Wikipedia, pre-Facebook age. h2g2 hasn't always had the resources necessary to be at the cutting edge of the technology it pioneered all those years ago, but its Community remains as strong as ever and the number of Edited Guide Entries grows daily.

In a recent thread, we asked you what you think h2g2 does well and we're still getting interesting responses. From:

Whether good or bad, it's quite clear that a lot of you regard h2g2 as still a pretty unique place. We are inclined to agree, so - here's to the next decade!
