To the ed.
While i'm sure these diagram articles are very interesting to some, can you stop pushing them onto the main Register RSS feed... they're not really that newsy.
Installing the software is just the start: you can also buy all manner of diagramming add-ons and alternative stencils, templates, shapes and icons either from your vendor or from third parties. The beauty of the third-party market is that it is huge, flexible and offers plenty of cheap, or even, free software. A quick word …
Ahh I get it, its advertising.....
Unlike the chap above I do like these type of articles and I am only really a main page whore so I would miss it if it were shifted feed. I do however like articles with maybe a bit more than here. I original expected to find the article telling me about all the different diagram tools there are (or a bunch of them anyway), and maybe recommend a few for specific jobs. You know, maybe talk about there pro's and con's.... that sorta thing.
Just my thoughts.
Visio's not my thing and hasn't been for a while. Its UML diagrams are overcomplex, too Java-centric (as in, the types) and too inflexible. Recently had to edit a technical doc in Word with embedded Visio objects. Never was able to really edit the embedded Visios, they were all mangled when brought up in the editor. Plus, really it takes so much time, not simple enough.
A long time ago, ABC Flowcharter was quick at knocking out basic flowcharts. That's what I need, speed with less handholding and exactness. And less $$$ as well.
FWIW my current toolset, when appropriate, is using the Dot programming language, which is basically a declarative text-based language used to define graphs which are rendered separately. Quite powerful, open source and works on Nix, OSX and Windows.
Diagrams are powerful, yes, but Visio's not the tool, IMHO.
