Twitter off-line reading

[SarfEasticated]

I read my twitter on the tube on the way to work. At the moment if I see a link i want to read, i open it in safari and then download it when I get to work. Is there a better way of doing this? can i mark the tweets and then find them easily when I get above ground?
What's the solution oh techy peeps? Surely there is an app for this?

I just favourite tweets that have links I want to read later - works like bookmarking them.

Thanks exexpat :)
