I've all but migrated to Instapaper from ReadItLater, but can't accomplish the import and am bummed by the options of using both for a while or (gasp) manual click-add import of a couple of hundred links.
Any other ideas?
1st get the RSS feed from ReadItLater. Then register in Instascriber using your Instapaper username & password. Add ReadItLater feed to instascriber. Now you can get your ReadItLater feed to Instapaper, at least most recent links
