Marc Andreessen, one of the original developers of Netscape (remember that?), has announced that he is backing the new browser start-up ‘RockMelt‘. While not released yet, could this browser add to the steadily growing list of those we web-developers must use for our standard site-checks? The last year or two has seen an increase in that list which now includes multiple (and very different) versions of Internet Explorer, Firefox, Safari, and recently Google Chrome. While RockMelt is just a name right now, the fact that the New York Times is prominently covering the announcement might be indication that the browser could get enough traction out of the gate to matter… Or maybe this will be the only mention you will ever hear of it.
