Can it be a money issue? Remembering that WhatsApp is not free, the 1$ for a year of service should be how they make money (I think they did a very good job there because no one that I know remembers that). Maybe the on-line phone solution suits them technically and economically, because they don't want to provide you with an alternative client that you might use for free. As they say this is simply and extension of the phone client.

I don't think it's that no-one remembers that, but I don't think WhatsApp actually enforces this seriously. I have never paid for the service and each time the deadline for doing so approached, it had been extended.

I've paid for it once, but before that I had at least two extensions, and since I paid I've had one extension.

Hello, I made this simple app to help me whenever I'm reading some journal article. I always want to give a quick peek at some referenced article but searching google for the citation almost never gives me a link to the right article, and copying and pasting is always quicker than filling some database archive's search form.

I really like the regexp matching approach because is fast and doesn't need any database at all, the downside is that not all publishers' websites have meaningful urls :(

I choose Flask to make this because I am learning python for my work and Flask seemed to be really easy to make a one-page app like this, and indeed with very few lines of code and trips over to the documentation I was able to pull this off in the weekend.

Tell me what you think and feel free to suggest any improvement or addition, i would really like this to be useful for more people than the ones that live between the four astrophysics journals I implemented :)
