From the East Bay Express:
It’s hard to pinpoint a single killer of citizen journalism — more likely, it’s a whole concatenation of factors. As it’s become increasingly clear that the costs of launching and maintaining a blog outweigh the benefits, many erstwhile bloggers have shifted operations over to Twitter, or attempted to parlay their skills into a full-time job for a mainstream media outlet. (Such was the case with Alex Gronke, who founded The Oakbook, and eventually became a regional editor for Patch.)
But neither explanation fits VSmoothe [a local blogger] who tweets only sporadically. Perhaps the end of A Better Oakland is just another grim harbinger of doom for the local blogosphere. Once considered an auxiliary — in some instances, a substitute — for an ever-shrinking pool of newspapers and media outlets, it’s become largely moribund.
You see, it’s NOT so much Facebook and Twitter. Although I do think some bloggers are giving up blogging for these formats. I think it’s the bloggers themselves. I think with a little ingenuity and some hard work, blogs can keep going.
