One of the coolest features they introduced is the ability for a presenter to have a audience of web devices that now auto-update when the user is logged into the event url and allows them to provide feedback or participate. Having used other physical devices, the usability is simple and everyone can participate, granted they have wifi or a mobile device with a modern browser such as iOS, Android, Blackberry, etc.
They have another tool currently in development called Sentimatic. This will allow you audience to give you instant feedback on your discussion. http://sentimatic.com/GOfundme.com is going into a public beta and it looks to be a great way to instantly setup a site to collect and raise funds for your event, dreams and causes. Check it out at http://www.gofundme.com/. The site charges $9 per month and does not take any additional fees per donation. The site utilizes the PayPal API for transactions.

If you are looking for a tool that can help you track your web sites and alert you if your site is having a problem then you need to check out http://www.AlertMySites.com. The site offers several options, including a free service. Based on your needs they offer an iPhone app for monitoring as well as e-mail, Twitter and SMS support for getting an alert if your site goes down. You also get a follow-up alert once the site is back-up and running to confirm the service has returned. I had been running an older Mac based service which no longer is support and we had tested several web based solutions over the last several months and I loved the options, pricing and solution here. Monitoring can be setup to test a particular url or for a word on a particular page. You can also get warning if the site times out or does not respond.

I selected Tech as the categories and you can see a list of topics.
Once you find a topic of interest you can bookmark that url such as http://gadgets.alltop.com and you can visit the updated content daily. Moving the mouse over a headline displays the opening of the web site.
I would recommend checking out these (to get started)

Check out from an web 2.0 application stand point, this site is amazing. It takes the concept of blogging or maintaining a web site to a whole new level by allowing you to easily e-mail just about any type of content and it will auto build the page or entry for you. It could not get any easier. The design of the site is beautiful and clean. It the first major web site that has truly amazed me in the past couple of months and its a great new tool to use to share, blog or post content. The site will auto post the same info, if you want to twitter, flckr, as well as all major blogging tools. I highly recommend giving it a test drive and I'm sure you'll jump on board. http://is.gd/eNfP
