Linked data browsers?

Hi,

I'm wondering what Linked Data browsers people are using these days.

I find that:

Openlink (http://demo.openlinksw.com/DAV/JS/rdfbrowser/index.html) 
only loads inside Firefox some of the time;

Objectviewer appears to be defunct;

and Disco and Tabulator both seem to parse irregularly. 
(For example, neither are showing any triples for 
http://dbpedia.org/resource/Berlin)

Am I doing something wrong? Or has the world moved on?

Many thanks -
Joel.
