opera, just enter all of your user rss feeds into an OPML file and bulk load into the browser RSS function. Hell, if you want to put them on a WP blog after that, or other email accepting poster, then simply right click on the rss title in your browser, and click "redirect". You can then email it to your blog "or even another tweet account". Throw in a dash of cron, and a liberal dash of Sikuli Jython (for desktop automation), and you have a scraper-poster with a lot of flexibility.
