Memeflow Goto is an AJAX-based service that allows you to build your own homepage. It’s a little bit cluttered in my view (why see URL, title, X and # on every single item – it’s so visually dense) but still promising.
There seems to be an appetite for this homepage stuff, and Microsoft, Google and Yahoo! already know that. Look forward to plenty more of these kinds of services from eager programmers in the coming months.
