Take a look at the screenshot of an average Twitter page.
Now take a look at this screenshot.
It is standard practice for Twitter to enlarge the font of the last tweet you post, so that the tweet on top has a larger font than the ones below it [picture 1]. However as seen, if your tweet contains some specific keyword, such as Gaza in this case I suppose, the tweet remains with enlarged fonts even after a newer tweet has been posted above it [picture 2].
The misery that Hamas has brought upon its own people who had elected them to power in Gaza by continually provoking and launching attacks on Israel should be highlighted and brought to the notice of more people for increasing the awareness and opposition to Hamas terrorism.
Small changes such as the one made by Twitter could play an important role towards coming up with a viable solution to the problem facing Israel from Islamic terrorist outfits like Hamas and Hezbollah by generating awareness.
