I think so. This is especially true if the visitor happens to be underage.

The first time that I saw my IP address and city posted in a widget of a blog that I had landed on, I was outraged. When I visit a site, I only want the webmaster to know my IP address, not every person visiting the site.

If a site uses a widget that displays visitors' IP addresses, they should receive warning of that before they actually are redirected to a page that does that.

And, really, what purpose does this traffic widgets serve? When they're visible to every visitor on the site, nothing. When viewed by the webmaster, of course the webmaster could obviously use it to find out how visitors are landing on his blog. However, putting traffic widgets on any public page is just an attempt to fill empty space, or if the widget contains links to the site that the user came from, an attempt to grab some PR juice.

Just thought that I would share with you an article that I came across about a new worm referred to as "Downadup" or "Conficker," which has spread to more than 9 million computers in less than 3 weeks.

Here's some info from USA Today:

The worm takes advantage of a security hole that exists on hundreds of millions of Windows PCs. Microsoft issued an emergency patch for the hole in October...

The worm first appeared on Jan. 7. Tech security researchers say it probed for and implanted itself on any unpatched Windows PC. It then scanned for, broke into and infected all nearby computer servers. It also implanted itself onto any portable device plugged into the PCs' USB inputs, such as a thumb drive storage stick, an iPod or a digital camera. When the corrupted device was plugged into another computer, that machine became infected — and began searching for other PCs to infect...

The National Cyber Alert System of US-CERT advises corporations to disable a Windows feature, called autorun, to help cut down infections from USB devices. Microsoft has a cleanup tool available. But the worm blocks Internet traffic trying to get to Microsoft's tool.

So, if you have set Windows Automatic Updates to not install updates automatically and haven't installed anything since January 13th, you should go ahead and take care of that now. In fact, if you have any updates that are waiting to be installed, install them now. Keeping your computer patched with the latest updates will help shield your computer from viruses like Downadup / Conficker.

Well, it just depends on the type of visitors that come to your site. I really only see video comments bringing anything of use to your blog if the video comment:

1- Is a how-to video
I mention the need for interesting video comments below. You can't go wrong with how-to videos.

2- Is something that you visitors would consider entertaining or interesting
This is very important! Do you want your visitors bored by your other visitors' boring comments? You can spot a boring typed comment easily and choose to ignore it without wasting too much of your time. But, a video comment requires some type of effort from the person choosing to watch the video. Think about it. Wouldn't you be a bit annoyed if you hit play and found the video comment to be uninteresting?

3- Contains something that can not be typed out in a normal comment
This is the most important rule of all when posting video comments. So many people waste time uploading things that they could have typed in a normal comment. Do you really want 10 video comments of your visitors going back and forth saying stuff to each other that they could have just typed in a comment?

So, what do you do if you're allowing video comments, but don't want it to get out of hand? The best thing to do if you allow video comments is to warn visitors that their video comments may be moderated. You may even want to have a policy that restricts video comments to things like how-to videos or prevents users from posting video comments of themselves saying as trivial as, "Hi!"

Me? I'm going to stay away from it altogether. If my visitors have something visual to share with other visitors, they can provide a link. Otherwise, it can be posted in their comments.
