Stop the bad math on alternative energy

I think it's important that we stop burning petrofuels or indeed any fuels and get energy from better sources.

But there's a disturbing phenomenon I have seen from people who believe the same thing too much. They want to believe so much, they forget their math. (Or I may be being charitable. Some of them, trying too hard to sell an idea or a product, may be deliberately forgetting their math.)

I see this over and over again in articles about photovoltaic solar, wind and other forms of power. They suggest you could put in a PV panel array for $20,000, have it provide you with $1,000 worth of electicity per year and thus "pay for itself" in 20 years. Again and again I see people take a series of payments that happen over a long time and just divide the total by the monthly or annual amount.

Please don't videoblog (vlog)

At the blogger panel at Fall VON (repurposed to be both video on the net as well as voice) Vlogger and blip.tv advocate Dina Kaplan asked bloggers to start vlogging. It's started a minor debate.

My take? Please don't.

Why do people put angle brackets around <urls>

Quite frequently in non-HTML documents, such as E-mails, people will enclose their URLs in angle brackets, such as <http://foo.com> What is the origin of this? For me, it just makes cutting and pasting the URLs much harder (it's easier if they have whitespace around them and easiest if they are on a line by themselves.) It's not any kind of valid XML or HTML in fact it would cause a problem in any document of that sort.
