If that large follower base (count of people following you) on Twitter gives you a high, here’s a tool that might break your heart, a little bit at least.
Called TwitBlock, the tool will scan profiles of everyone who follows you on Twitter and it will then prepare a list of Twitter accounts that may be fake or have been created with the sole purpose of spamming Twitter.

For my Twitter account, the tool flagged some 354 accounts (or about 6%) – a lot of these accounts are spam for sure but there are some real people (human beings) and legitimate bots in the list as well so be a little careful before you block any user. Here’s the full spam report generated by TwitBlock.

If you were new in a city and looking for something to check out, Layar might well be worth the time (and battery drain) to check out. Who wouldn't want to check out
