Amazon.com Inc, the world’s largest Web retailer, launched Askville.com, an information-sharing Web site where users can ask questions and answer queries from others, on Thursday.

The site, open to all of its customers, has been in beta testing since December 2006 and has already been open to a few users, Amazon said.

Similar services are offered by Yahoo Inc’s Answers and other Web sites such as AnswerBank.

Google is experimenting with Digg style voting features on search results that allow users to vote up or bury search results they see.

The program, part of Google Labs, works like this:

This experiment lets you influence your search experience by adding, moving, and removing search results. When you search for the same keywords again, you’ll continue to see those changes. If you later want to revert your changes, you can undo any modifications you’ve made.

At the moment the results of the program will only be stored per user and not applied to the general search index, so that sites buried (”I don’t like”) will not appear in future results for the user, where as sites voted up will stay up. Google Labs notes that “this is an experimental feature and may be available for only a few weeks,”

The Pirate Bay just rolled out a new feature to their music section that makes it easy for users to find similar artists, more albums from the same artist and upcoming concerts. The data they are using comes from the popular music community website last.fm and is fully integrated into the website.

If you click on show detailed artist info on a torrent page it will show a list of similar artists, other albums from the same artist, upcoming concerts and even an embedded Last.fm player. The new features are inspired by the OiNKplus extension for firefox, but it loads a lot faster (instantly) because all the data is cached.

About group chat
The group chat feature lets you chat with many friends at once. There’s no limit to the number of people you can chat with, and any participant can invite others to join. To get started, follow these steps:

1. Start a chat with a single person in your Contacts list.
2. Once you’ve started the chat, click Options at the bottom left of your chat window and select Group Chat.
3. In the field labeled ‘Add a person to this chat,’ enter the name of the contact(s) you want to add to your group chat.

To end your chat, click the X at the corner of the chat window. Others in the group chat will get a message saying that you’ve left the conversation. If you want to rejoin, you’ll need to be invited back by a contact who’s still in the group chat. The group chat will continue until all participants have left.

Microsoft Corp.’s Windows XP operating system is about to get faster and Windows Vista isn’t, according to a report that caused a stir online this week as industry watchers speculated that a zippier XP could keep customers from upgrading to Vista.

Microsoft, however, said it’s too early to evaluate the two service packs it plans to release next year.

Early versions are already in the hands of testers like Devil Mountain Software Inc., which helps big financial services companies track trading-floor computer performance.

Wellington, Fla.-based Devil Mountain Software ran several versions of XP and Vista through a test simulating common desktop computing tasks. It found the original Vista performed 50 percent to 100 percent slower than the prevalent XP Service Pack 2, or SP2.

Vista SP1, due out in the first quarter of 2008, barely improved the operating system’s performance.

But XP SP3, scheduled for the first half of 2008, did improve on XP’s earlier performance, running 10 percent faster than SP2.
