SAN FRANCISCO (CBS SF) -Twitter may soon start looking more like Facebook. KCBS Financial Reporter Jason Brooks says the micro-blogger is testing a new look for its profile pages, which would resemble Facebook’s Timeline.

The changes would include more prominent photos along with larger fonts for tweets rather than Twitter’s current layout of 140 character updates.

The move comes after Twitter’s quarterly earnings report revealed a decline in its active-user growth, a big concern for investors given the competition in social media over advertising dollars.
