Some computer scholars have named them Web 2.0. Most are in the testing phase, so there can be glitches. With these sites, you only need an Internet connection. Special software is unnecessary. And the services run on both Windows and Mac. Plus, most are free.
Here are some useful Web 2.0 sites:
1. Free Office.
Microsoft Office is the de facto suite. But its various renditions cost several hundred dollars.
Zoho offers Zoho Writer, Zoho Sheet and Zoho Show. These are free counterparts to Word, Excel and PowerPoint, respectively. You won't find as many features as you'd find in Office, but there are just enough to be useful.
The sites are similar to Microsoft Office, so there are no big learning curves. All files are saved online. You can start a document at work and finish it at home.
All three sites open and save files in a variety of common formats. For example, Zoho Writer will open a previously created Word document, HTML or rich text file. It will also save any file onto your computer's hard drive as a Word, pdf, txt, rtf or html file.
Zoho isn't the only business offering. The ubiquitous Google has an online word processor and spreadsheet. Google purchased the word processor, Writely, which has been around for some time. Writely doesn't have as many features as Word, but it is certainly usable.
Google Spreadsheets is less complete than Zoho's program. It is fine for basic number crunching and the maintenance of lists. But it lacks the capability to create graphs like Zoho Sheet.
You need an invitation from a current user to sign up for the Google programs. Or, you can get an invitation online.
2. Online rÃ©sumÃ©.
Creating a rÃ©sumÃ© is difficult. But creating a good-looking rÃ©sumÃ© is even tougher. Emurse helps you create nice-looking rÃ©sumÃ©s that can be shared online or printed on paper.
You can either upload an existing rÃ©sumÃ© or create one. Creating one from scratch takes longer. But you have more options when done, such as the ability to edit and share it online.
Once a rÃ©sumÃ© is created, emurse will post it online for free. It also tracks where you've sent your rÃ©sumÃ©, offering reminders to follow up.
3. Family affair.
Personal Web sites and blogs can help keep families in the loop. But they're generally managed by one person. Jotspot Family Site lets everyone get into the act.
One person initially signs up for the free service. Invitations to other family members are sent through the Web site. Each family site is given its own Web address. Family members must sign in with a user name and password.
Any family member can add photographs, birthdays or important dates. There's also a section to share recipes and a blog feature.
4. Share video.
Web sites like YouTube are great for sharing video with the world. But you may want to keep your family trip to the beach private.
Fliqz allows you to share videos with as few people as you want. It offers three security levels: public, private and private with security. Videos designated as public are accessible to anyone. Private videos have unique Web addresses. Only those who know the addresses can access them.
"Private with security" videos also have a unique address. In addition, visitors need a password, which you set.
You can store and share an unlimited number of videos. However, each upload is limited to 100 megabytes (10 - 15 minutes of video).
