New! Upload Word Documents & Excel Sheets to Slideshare
Slideshare, a service often referred as “YouTube for Presentations”, has expanded beyond PowerPoint slides into other territories like Word documents and Excel spreadsheets.
You can now upload both .doc and .xls files on to SlideShare in addition to PDF and ppt format.
This brings Slideshare in direct competition with other document sharing services like Scribd, DocStoc, Zoho Share and, to some extent, eSnips.
Comparison of Document Sharing Services
| Scribd | Slideshare | DocStoc | Zoho Share | |
| File Size Limit | ? | 100 MB | 50 MB | 3 MB |
| Allows Anonymous Uploads | No | Yes | Yes | No |
| Supports Office 2007 Formats | Yes | No | Yes | No |
| Flash Viewer Size (for embedding) | 127 KB | 29 KB | ? | ? |
The following Google Trends chart compares the traffic across different document sites but it may very-well change in future as Slideshare has ventured into waters that were earlier dominated by Scribd.

Like other document sharing services, Slideshare too converts your Office documents in Adobe Flash format for viewing or embedding but they also create a plain text transcript of the document that spiders can read and understand. Therefore any content uploaded on Slideshare has a better chance of ranking in search engines.
