Silicon Valley investor and once-prolific tweeter Marc Andreessen is back on Twitter with a new avatar - it's a bald Charlie Brown clutching a book - and a summer reading list.
Andreessen, cofounder of buzzy venture capital firm Andreessen Horowitz, abruptly left Twitter in the fall of 2016, deleting all his tweets after writing, "Taking a Twitter break!"
The early Facebook investor and creator of the first popular web browser had been well known for his authoritative Twitter presence, firing off tweetstorms and retweeting messages about tech, economics, and politics, at all hours of the day. Andreessen has nearly 700,000 followers on the social media site.
Now he's back, if only to share a summer reading list.
He tweeted on Thursday, "Thread: Books I've recently read and recommend."
