I think that the two initial comments are more about poking fun at the messenger than addressing the message, yes web pages have typo'sand links between sites can be down. The connection problem seems to be on the University of Berlin end, not linked data.
My point is that this initiative has momentum and a number of enthusiastic followers, where is the momentum and where are the enthusiastic followers behind LSID's?
One of the standards in linked data is that URI's should not change and they have a number of good recommendations on how to mint them and persist them over time. Some of these would apply to minting LSID's.
It is one thing to design a standard or technology, it is quite another to get others to adopt and use it.
You might want to consider who has had more success in developing widely adopted standards Tim Berners-Lee or TDWG?
I may be relatively new to TDWG and Entomology but I am not new to biocomputing or the issues involved in developing tools or techniques that are widely adopted.
My assumption is that you want to develop a standard that is widely adopted, and that will involve addressing the concerns of potential adopters. My main needs involve tying species concepts to observations, environmental and other data. The TWDG standards have not been very helpful to me and the reliance on LSID's is one problem. Those implementations that are available do not really work. Does uBio deliver properly encoded data? No, at least not always.

I think you'll find plenty of people who will argue that the cost of minting persistent GUIDs is much higher than the cost of a web server and domain registration in any event, and that it might be a Good Thing(tm) if an identifier system doesn't pretend otherwise.
[...] 4) Tim Berners-Lee feels that LSIDs are unnecessary, and after
spending several years looking at this issue I think he is right. Even if TBL is wrong, you have positioned yourself for an uphill battle for adoption.
He has been wrong before. More to the point, I don't think this has to matter. In 1998 he would have probably said that DOIs are unnecessary. They may indeed be, from a technological standpoint, but from a social and business (sustainability) standpoint they've clearly been hugely successful. So I think the question that matters much more is, is there (or will there be) a similar ecosystem and environment for LSIDs that will make them equally useful. That's what I'm less sure about.
Also, I think we ought not to confuse one use-case for GUIDs (such as linked data) with the requirements for an identifier system for biodiversity.
-hilmarBTW if anyone feels this is a long discussion that has been had before, check out the thread that begins with "registering info: uris" on the Code4Lib list (http://www.mail-archive.com/code4lib%40listserv.nd.edu/) It turns out they struggle with similar questions (and also not for the first time), except in a library context, which might be much closer to a museum context than a semweb research community.
