Try one of my experiments:

• Domain Search
• Tweets Ahoy

Both are part of my ongoing efforts to get to grips with JavaScript as both a client-side and server-side language. Tweets Ahoy is completely client-side and makes use of the excellent Twitter Search API. Domain Search has both client-side JavaScript and server-side JavaScript, the latter via node.js.

Alternatively, try out my Google Chrome extensions:

• CheckCom - check if current url has an available .com domain
• CheckNet - check if current url has an available .net domain
• CheckOrg - check if current url has an available .org domain
• Profanisaurus - replace potty words with glorious dinosaurs!

Feeling more frisky? Try this Safari extension:

• CheckDomains - check if current url has available .com, .net or .org domain
