4. Dexter the crime-fighting dog
Dexter lives a good, moral life by helping out U.K. police do their job on the Web. By sniffing out danger, he helps the police in investigations. But on a semi-serious note, the U.K.'s Get Safe Online unit notes that Dexter cannot sniff out malware and online nasties unlike a good, strong anti-virus solution, and takes the day to remind online 'fools' to be wary of online criminals.

5. Google 'sniffing out' search results
Yet another Google prank for April Fools' Day, as the search giant goes all out on its range of stunts, spanning social networking, mapping and video. And its core search business is no different.
Google "Nose" probably didn't have many fooled, the concept is interesting, allowing users to search for smells and have it fed back to them via their smartphones. Even "don't ask, don't smell" features are included for the more nefarious, not-safe-for-work Web results.

6. "Emotion" thoughts with Google+
Social network Google+ now allows you to add additional "emotion" thought bubbles to your uploaded photos, adding a little more thought to the picture. With one click of a button, you can now 'see' what people are thinking. At least, sometimes.
