What is your point exactly?

Of course there might be security flaws in my code, but this completely open source software, hosted on gitorious.
The code is not only public, it is also very short: about 700 lines for the text mode client, and an extra 800 lines for the gui.
This is important, because the shorter a program code is, the easier it is for other people to review, and this increases safety.

I decided to write and release the server code too, because I wanted to give as much power as possible to the client users, so that they are not tied to a particular server operator. For this reason:
1. the server is open source
2. clients do not need to open an account at a server in order to use it.
These two points make Electrum different from other thin wallets projets that I know of.

why? a single server can be shared by thousands of clients.
if this service becomes so popular that servers cannot handle the traffic, then they could also charge for the service; it would probably cost less than transaction fees.

the server cannot steal your bitcoins, because it does not have access to your private keys. all it can do is misinform you on your balance or transactions. However, it would be easy to compare the information returned by several servers, in order to detect a discrepancy.

The seed (passphrase) should be long and random enough that it is completely impossible to guess.
The client refuses a seed shorter than 20 characters. Fortunately, you need to type that seed only once, when you create your wallet.
Once you have created your wallet, you encrypt it with a password, and that password can be shorter. If you forget your password, you can still recover the wallet from the seed. If you forget the seed, you can recover it from the wallet file and the password.
edit: the seed is now generated automatically; it is believed that users-provided passphrases are not strong enough

No. This is completely impossible, because the server does not have your private keys.

I will make more screenshots and post them on the website. :-)

The "Board" tab displays a welcome message that is sent by the server.
It can be used to call for support donations, to display some third-party advertising, or any kind of evil propaganda, depending on the server operator's business model.

The server if a full bitcoin node, that has been patched to distribute transactions signed by the clients.
To operate a server, you need to run bitcoind + bitcoin-abe + Electrum's server script. In the future, it might be simplified with libbitcoin

alpha version is ready.

[updated october 2012]

Electrum is an easy to use Bitcoin client. It protects you from losing coins in a backup mistake or computer failure, because your wallet can be recovered from a secret phrase that you can write on paper or learn by heart. There is no waiting time when you start the client, because it does not download the Bitcoin blockchain.

Link: http://electrum.org

Features:
*  Safe: Your private keys are encrypted and stored locally.
*  Forgiving: Your wallet can be recovered from a secret seed.
*  Instant on: Your client does not download the blockchain, it uses a remote server.
*  No downtimes: Several public servers are available, you can use any of them.
*  Ubiquitous: You can the same wallet on different computers, all instances remain synchronized.
*  Tested and audited: Electrum is open source and was first released in November 2011.

Slashdot it; it's legal, and as efficient as DDoS.
(the problem if you do that is that .com too will be slashdotted)

There is no data supporting this claim.
You are trying to associate Bitcoin to illegal drugs in the mind of forum readers, with no proof whatsoever.
What is your agenda?

I don't think this is in the bitcoin roadmap.
You could use this website: http://ecdsa.org/annotate

so you own more that 1% of the bitcoin supply?
unless you provide a proof of what you say (a message signed with the private key of the bitcoin addresses with your coins), nobody will trust you.

woot! I updated my signature :-)

they now accept bitcoin:

unfortunately java is not my favourite language.
I guess I will try to do it from scratch in python, using bitcoin-abe + bitcoind at the server side.

they face hosting costs, which is something that can be paid in bitcoins...

there are other options, check the Trade page.
the OP asked for recommendations, not for a comprehensive list

ok, I have decided to implement this idea.
are you willing to share the server code ?
I would be interested in the communication between your server and the bitcoin network (propagating transactions)

Diaspora is a project that I really would like to see succeeding.
Let them setup a bitcoin donation address, I'll be donating :-)

thanks for the comments. I have added a short explanation at the top of the page.

For the moment, this page is updated manually; I might try to automate it later if there is some interest.

A Gaussian kernel would certainly erase some information. Due to the random nature of bitcoin exchange between individuals, I expect the blue distribution to become smoother in the future; (as a consequence of the central limit theorem).

here is a function that you can use:

I can add a callback function if you need to do it in javascript

oh you are right, it's not coins/block but coins/(intervals of 10 minutes), so it fluctuates around 50
I will fix that

yes the blue lines are very tall, this is why they are cut.
if it was not cut, the area under the green curve would be equal to the total area in blue

This animation shows from which point in time coins have moved and stayed unused.

The green curve shows generated coins, the blue curve shows when they were used for the last time.
