The Web is crowded with online presentation sites these days, so there is no excuse for not publishing your best presentations and slide shows for the rest of the world to see. Publishing your hard work to the Web is a simple process that enables you to get some attention and store your files online rather than on your hard drive.

Here is a list of some of the most popular online presentation websites available:

1. Zoho Show 2.0: This online tool helps you to create powerful presentations, with pre-built themes, clipart and shapes, along with easy drag-and-drop features.

2. Google Docs is probably the most popular online presentation service, and resembles an MS Office Suite with its choice of document, form, spreadsheet and presentation tools.

3. Slideshare is quickly becoming one of the Web's key players in online presentation tools. The site permits you to download most commonly used presentation files, sign up as a member, and publish your presentations on the site. You can also link up with other members, share your favorites, and browse through its many slideshows on a myriad of topics.

4. Prezentit also provides users to download, share and publish their presentations. Like the other sites here, Prezentit permits you to work with your team on the same presentation at the same time, gives you a unique web address for the presentation, and allows you to upload them back onto your hard drive, if you want.

5. 280slides is a hot new Web 2.0 site where you can download, upload, create and publish your presentations. 280slides has been praised for its cool-looking presentation themes, so you might want to check it out if you're looking for something new.

6. Sliderocket allows you to present your slides at meetings on the web in real time, and embed your presentation onto web pages and blogs -- as do most of the sites mentioned here.
