Descriptor is generally correct in stating that it's primarily a greasemonkey site; note the default user icon is a larger version of the (adorable) greasemonkey logo. But he also said "... and other ways of remixing the web."; as a result, greasemonkey is assumed but not required. The main reason to specify opera, though, is that not all javascript implementations are the same, so javascript code that works on one platform may not work on others, especially if it involves xpath or xmlhttprequest calls. The upshot is that a firefox script may not work correctly on opera or IE or &lt;insert browser here&gt;, so anything other than the default (meaning most recent versions of firefox and greasemonkey) should be stated. -Joel <p>Descriptor is generally correct in stating that it's primarily a greasemonkey site; note the default user icon is a larger version of the (adorable) greasemonkey logo. </p> <p>But he also said "... and other ways of remixing the web."; as a result, greasemonkey is assumed but not required.
