I hope to build on this news item and post similar sites that do the job of one site that posts to all social media sites.
http://spnbabble.sitepronews.com/ - from there blurb -
‘SPNbabble is a micro-blogging service that enables you to share comments, tips, and insights with friends and colleagues here as well as on Twitter, Friendfeed, Plurk, Tumblr and Facebook.’
Any good? – Early days. As a micro blogging site, it seems fine, but as a ‘one stop shop’ for all social media, i think it needs to include more social media sites, which i don’t think will happen any time soon. Maybe worth a try though.
If you find such sites, please email them!
