It really depends on how its being read. Excel™ (for example) will let you do a fast read of .csv files that doesn't require any configuration. It lets you do this right from the file->open... dialog. On the other hand, Excel™ will probably let you use the import facility to import pipe delimited files as well. It will just take a bit more work.
That said, if you want to produce a file that almost anybody can read, you probably can't do better than to export the CSV documented in the article. One caveat: many non-US countries are configured to use a semi-colon as a comma. People in these countries have to change their international settings to read CSV files that are delimited with U.S. commas. At least if they want to use their normal, easy, file->open... dialog to open the CSV file.
