While Twitter has achieved a certain mainstream appeal in the geek-savvy community, the omnipresent whale stands to make players out of Friendfeed, Plurk, Pownce, while denying Twitter any hope of crossing into general societal mainstream use. The same mainstream use that Facebook has had for some time now – put it this way, if one of your parents, aunts, uncles, or grandparents has a Facebook profile, you know we've "crossed the breach".
While I've certainly loved the open approach that Facebook has taken with letting developers create some fantastic (and a whole slew of absolutely craptastic) apps and profile boxes, my biggest complaint for the past year has been wading through the endless Fun Walls, Super Walls, Scrabulous stats, Compare People lists, Super Pokes, and ILike icons to find something on MY OWN PROFILE. (Yeah, I know I could click those little icons up at the top left to get to the widget I want, but I've got half of them buried)
The preview build of the new Facebook profile template has become more portal-like, reminding me of i-Google ability to have tabs for different content, allowing for the front page to contain your wall and some of the other vital profile stats. While I'm sure there will be some purists who will complain that their friends will now have to expend energies that extend beyond a scrollwheel to "give you more cowbell", the redesign is sure to cure some of my persistent scrolling headaches. I don't know how customizable they plan on making the tabs, but I'm betting that Facebook (with its MS funding) is going to try and take a run at being your new homepage/portal. When they make it simple to create your own RSS feed widget, like in I-Google, the game will be afoot.
