Twitterers Worldwide Gather for Twestival

Ms. Rose said she hopes the larger-scale event in London can raise at least $4,000 — enough to dig one well in a developing country. In total, she’s aiming to clear $1 million in donations, though she’s said she doesn’t want to put pressure on the smaller gatherings. A million may sound like a lofty goal, but so far Twestival has collected more than $10,000 in donations via TipJoy, an online micropayment system.
