Something that needs to update so frequently shouldn't poll for its data. It would be a better idea to create a Comet server. That simplifies synchronization since you don't have to query the DB every time someone does a request. Instead, you query it every time someone changes a field.
I think you hit the nail right in the head when you mention all these different services. There are many products out there that expand our features, however using and mashing these products together ends up with a complicated and difficult to setup service.
We picked features that are useful for non-techies and made them accessible through a single interface.
We think that there are many users that want a web page for their group but don't want to interact online. GroupieGuide is a gets out of the way solution where most of the interaction can be done over e-mail. Visitors don't need to navigate to get the information that they need.
Both ning and tangler focus on building online social interactions through the website. We are trying to cater to the users that have been ignored by social networks.
It benefits everyone when individuals speak on the language that they feel more comfortable with. If what they have to say is valuable it will be translated to other languages anyway.
I made a light version of haml for javascript called baconl. It doesn't support embedded code, but I have found that it is not needed when used with most javascript frameworks.
If you select the 9+6 and then insert the opening parenthesis it will wrap everything automatically. This is not really intuitive, but the extra idiocy is there for a reason.
I agree, seeing all of the documentation on the same page helps you learn other functions that you might otherwise not look at. Also, the higher level the language the less the programmer has to rely on autocompletion.
"At over 100,000ft the balloon lost its inflation and the equipment was returned to the earth.
"We travelled 10km to find the sensors and photographic card, which was still emitting its signal, even though it had been exposed to the most extreme conditions."
Like with many other measures to prevent piracy, the crackers would find ways to remove the morality reminders and the paying customers would get stuck with them.
Lua is a multi paradigm programming language that is very popular with game makers. There's also an engine written in Lua for making 2d video games called Love http://love2d.org/.
A few years ago there were some papers about logging keystrokes by recording the sounds of the different keys in the keyboard.

HTML validation is of great value when debugging, even javascript. It can discover things that are easy to miss like unclosed tags and repeated ids.
It is difficult to write a whole website, validate it and fix the errors and at this point validating has little value. However by validating periodically you are getting more out of the tools available. I don't force myself to write 100% strict HTML, but minimizing the validation errors means that I will have less to read when it's time to.
When I was looking for internships I would just look for startup lists on cities I was interested in. I saw their open positions and sent a mail with my resume and a well crafted cover letter based on what I was interested on. Most companies were very accessible and would at least reply back.
TODO list, fullscreen and markdown support are amongst the ones I use the most.
