Google Sitelinks usability:
1. Google increasingly recognize us, means the level of interest our blog google eyes growing
2. Sitelinks can be a prestige for bloggers / webmasters, this is because Google does not explain alogartima provision of sitelinks and still be the step.
3. Can dominate the keyword in the search results.

Additional :
Not always blogs that have sitelinks will last, sitelinks can be lost like PageRank and Alexa in the search results. Apart from all that live how we maintain what we already can. As the proverb says retains more difficult than won.
