Random Little Things You Probably Didn’t Know About Londonist
Londonist is not just confined to the web. In fact, we have been known to branch out and put on events in the real world too. For example, you could join us on Monday 24 June for part O of our alphabetical pub crawl series, where we will be visiting the best watering holes Old Street has to offer (as nominated by you, our readers). Or you could submit an entry to our Time Travel London competition, which we hope to turn into a public display like our current exhibition of Subterranean London at Bishopsgate Institute.

London Weather, by Inclement Atlee
Another day of blue, sunny skies. The Weather Gods are going through their "2 Unlimited" phase...they've found a winning, repetitive formula that everyone seems to enjoy. But it won't last. In the same way that a resurgence of guitar-based indie-rock pushed aside acts like 2 Unlimited in the early 90s, a re-mustering of cloud and murk will once again take hold with the coming of a new week. In Summary: Work your body, baby, work your soul, I'm a workaholic when I'm on the floor.
