Following yesterday’s news that Twitter will be raising another round of funding based on a $250m valuation, Kara Swisher makes another argument for why Facebook should take another run at acquiring Twitter:

“Why? Because:1.) The pair actually do fit nicely together, creating the most powerful universal address book ever, and pairing the two fastest growing social-networking assets on the Web.

2.) While the likelihood of Facebook going public anytime soon remains dim, due to the weak economy and lack-of-enough-revenue issues, the idea of Twitter doing so is laughable.

3.) Some larger company, I would bet my favorite Barry Manilow album, will eventually buy Twitter–my vote would be Google (GOOG)–but higher valuations make an exit harder. Before that happens, Twitter should get itself the home where it would have the most autonomy and influence, which still is Facebook.”

Om Malik disagrees, saying Twitter could do and be more on its own, if its execs eschew the easy option of acquisition:

“While Facebook’s system is closed, startups like Twitter and lesser-known FriendFeed have an opportunity to create more eclectic environments that blend the best of the web. Twitter has the opportunity to help foster a more democratic ecosystem in which multiple Twitter feeder services can live off the platform.”

Meanwhile Paul Boutin writing for The Industry Standard speculates as to Twitter’s burn rate, trying to answer the question:

“How much does it actually cost to run Twitter, and how will that number grow ever more rapidly as more customers sign up?”

Elsewhere on the web:

Websense Security Labs reports that malicious hackers have registered bogus user accounts on My.BarackObama.com to spread malware around the web via the social media driven online community.

Laura Oliver at Journalism.co.uk reports that Trinity Mirror is going social, adding a range of interactive content sharing tools to its newspaper websites as part of a deal with social media firm Pluck, which provides similar functionality to The Guardian and Sky News websites.
