Over at EdWize Leo Casey chastises Eduwonk for not having a comment feature. Another reader recently asked the same question and it comes up from time to time. Been meaning to post on this so here’s the quick and dirty answer:
It’s been looked at a few times since the blogs inception but the cost-benefit just does not seem worth it. A lot of blogs that have them seem to have trouble with them. For instance just recently Joanne Jacobs’ site was down for several days because of a spam attack and the comment features on some blogs are difficult to read (or at least difficult with some browsers). Other bloggers relay similar hassles. Though the template for this blog was professionally produced, don’t be fooled…the day-to-day operations are just one person who knows next to nothing about how all this stuff works and has regular work deadlines and responsibilities to meet. Consequently, avoiding technical hassles is a high priority.
Content-wise, while there are some really interesting comments out there, just as much doesn’t seem to add a lot of value. Spam and promotions of other blogs aside, comments often seem to degenerate into name calling. We get too much of that in the regular ed policy debates, you surely don’t need a special forum for it. And, there is almost invariably a comparison to Hitler at some point.
Now if it was really hard to get your say or respond without a comment feature then the calculus might be different. But it’s not because the medium itself is democratic. It’s free to start a blog, so if you can post a comment you can have a blog of your own, and we happily link to interesting posts that challenge the ones here when they’re brought to our attention. And, despite volume, all correspondence gets answered and some gets posted on the site, too.
So, while it’s not a New England town meeting it’s certainly not Turkmenistan either. We’ll continue to look at the options, someone said the other day that Haloscan is the way to go. But, until then, start a blog of your own, send email, or save up everything you want to say for when we change our minds and add the feature and you can be the first one to crash the site with your voluminous feedback.

It encompasses a range of health care practices evolved to maintain and restore health by the prevention and treatment of illness.
Contemporary medicine applies health science, biomedical research, and medical technology to diagnose and treat injury and disease, typically through medication, surgery, or some other form of therapy.
The word medicine is derived from the Latin ars medicina, meaning the art of healing.
Though medical technology and clinical expertise are pivotal to contemporary medicine, successful face-to-face relief of actual suffering continues to require the application of ordinary human feeling and compassion, known in English as bedside manner.
As science and technology developed, medicine became more reliant upon medications. Pharmacology developed from herbalism and many drugs are still derived from plants (atropine, ephedrine, warfarin, aspirin, digoxin, vinca alkaloids, taxol, hyoscine, etc). The first of these was arsphenamine / Salvarsan discovered by Paul Ehrlich in 1908 after he observed that bacteria took up toxic dyes that human cells did not. Vaccines were discovered by Edward Jenner and Louis Pasteur. The first major class of antibiotics was the sulfa drugs, derived by French chemists originally from azo dyes. This has become increasingly sophisticated; modern biotechnology allows drugs targeted towards specific physiological processes to be developed, sometimes designed for compatibility with the body to reduce side-effects. Genomics and knowledge of human genetics is having some influence on medicine, as the causative genes of most monogenic genetic disorders have now been identified, and the development of techniques in molecular biology and genetics are influencing medical technology, practice and decision-making.
Sahachiro Hata discovered the anti-syphilitic activity of this compound in 1908 in the laboratory of Paul Ehrlich, during a survey of hundreds of newly synthesized organic arsenical compounds. Ehrlich had theorized that by screening many compounds a drug could be discovered with anti-microbial activity. Ehrlich’s team began their search for such a “magic bullet” among chemical derivatives of the dangerously toxic drug atoxyl. This was the first organized team effort to optimize the biological activity of a lead compound through systematic chemical modifications, the basis for nearly all modern pharmaceutical research.
Arsphenamine was marketed under the trade name Salvarsan in 1910. It was also called 606, because it was the 606th compound synthesized for testing Germany it was the practice to designate compounds by their development number. Another compound known commonly in Germany by its number is Parathion, which was the 605th compound to be developed in search for insecticide. It is commonly known as E605 (E stands for Entwicklungsnummer (German for “development number”)]. Salvarsan was the first organic anti-syphillitic, and a great improvement over the inorganic mercury compounds that had been used previously. A more soluble (but slightly less effective) arsenical compound, Neosalvarsan, (neoarsphenamine), became available in 1912. These arsenical compounds came with considerable risk of side effects, and they were supplanted as treatments for syphilis in the 1940s by penicillin.

Let me introduce myself. I am a Swallow Bird. I am an Internet newbie and ocasionaly find your site via search result.
It is awesome. Do you order the web design of your sit or create it without assistance? Looks nice. I hope I can create my own
site in the future. Here it is my first site bird feeders disease , bird feeders disease .
I enjoy the new article, very neat, i like this site
