Am i misunderstanding something about bitcoins? looking at http://blockchain.info/blocks/Deepbit , I see lots of submitted blocks, yet looking at the statistics page of the deepbit website, it shows no blocks for almost 2 days.. what's wrong? :/

is electrum safe for usage? the fact that it can regenerate my wallet from the a list of words i input (seed) is a little disturbing, but reading through their website of how this works, it seems secure enough. so i'm asking someone with better knowledge, if i can keep my seed secure, is electrum a safe enough bitcoin client?

PS: i do like the fact i can check my wallet without having to download the entire block chain.
