At the last class I gave on Open Source, someone asked me if there was a way to put social bookmarking tools behind their firewall. I didn’t know of any open source social bookmarking tools at the time, but now there is one (that I know of):

The social bookmarking service Ma.gnolia is announcing a new version at the Gnomedex conference in Seattle today, and the big news is that the whole thing is being rewritten from the ground up. M2, as it’s being called, will include all of the features of the current Ma.gnolia, but it’s going to be entirely Open Source. A first look at M2 should be available by September.

While this isn’t a new video, it’s a great post for this blog. I love Clay Shirky, he’s an amazing speaker! And speaking of love, Shirky makes a great point, the Perl is an act of love. The reason it’s so successful is because millions of people love Perl.

I wrote over at my other blog today about the exodus from Twitter to FriendFeed. One commenter pointed me to identi.ca as an alternative, but forgot to mention that it was based on open source software. This from OStatic:

Lots of people are addicted to microblogging service Twitter - including substantial chunks of some open source communities. There are a fair number of Ruby on Rails developers twittering these days, for example. But Twitter’s scaling and reliability issues lately have many people wondering whether it’s time to look for an alternative. Identi.ca, backed by open source package Laconica, wants to be that alternative.

I’m not making any switches right yet - but it will be interesting to watch how identi.ca handles the pressures that Twitter couldn’t.

Netvibes’ chief architect François Hodierne announced the opening of netvibes.org, a website dedicated to Netvibes’ Open Source projects: “By giving away our technology, we hope to foster innovations in the widget and personal-page space, and launch a discussion about their wide implementation.” Netvibes widgets are based on UWA, the Netvibes Universal Widget API. ‘Universal’ since UWA-based widgets run on any platform that supports common Web standards (HTML/JavaScript/CSS). That means iGoogle too.

We’re seeing more and more of this happening in the Web 2.0 world.
