Pros of Short Domain Names

Life is a good teacher. Up to now, it has never occurred to me a short domain name could be an advantage. I have always assumed, because I do it that way, people could bookmark a site when they like it regardless of the length of its name. Though I do not use it, social networking sites like Twitter changed my mind. I suddenly realized how difficult it must be to write a tweet about an article on this site without the aid of URL shortener services. Just writing the part "experimentsincyberspace/2009/04/" with the protocol prefix consumes 52 characters. I am not saying you will not be found. I am talking about the extra step, often tedious, of the necessity of shortening the URL. A very good idea could be having a short URL handy beneath or above your articles so that people can easily use it. Rather than having your visitors do it, you can take the extra step and place a short link yourself. In addition, keeping your URL intact can be a marketing and branding advantage.

A Thought Experiment on Do Follow Comments

Image
Einstein was a great scientist and without exception all physics students new to his work are introduced to his use of Gedanken Experiment or thought experiments. Gren Ireson, a lecturer at Loughborough University, UK, where his research interests include quantum philosophy, physics of sport and learning and teaching physical sciences, contests that a thought experiment has three requirements [PDF]: It is carried out in the mind (however one cares to define 'mind'). It draws on experience. It allows the experimenter to see what is happening (perhaps a better term to use than 'see' is 'imagine' or 'form a mental image').  I see a lot of blogs announcing they do follow comments lately, so I will humbly use Einstein's technique to shed some light on do follow commenting today. Let us start with a definition first. Google's Matt Cutts speaks: The nofollow attribute is just a mechanism that gives web masters the ability to modify PageRank flow

New Rush for Top Level Domains Begins

It will shortly, if ICANN's new proposal holds up, that is. According to Paul Levins, VP corporate affairs, any domain name will be possible, subject to your imagination, The familiar .com, .net, .org and 18 other suffixes — officially "generic top-level domains" — could be joined by a seemingly endless stream of new ones next year under a landmark change approved last summer by the Internet Corp. for Assigned Names and Numbers, the entity that oversees the Web's address system. Tourists might find information about the Liberty Bell, for example, at a site ending in .philly. A rapper might apply for a web address ending in .hiphop. [...] To beat a competitor to the punch, a company might decide it needs to control a new generic domain, such as .cereal or .detergent, but it would be costly. The currently proposed application fee is $185,000, plus an annual "continuance" fee of $25,000. If more than one company wants a suffix, there could be a bidding w
