The use of Information and Communication Technologies (ICTs) for information-seeking, social contact and leisure activities is increasing in adults and older people. However, little is known about adults and older people who are already actively using ICTs to write a blog. The aim of this paper is to describe the benefits adults and older people gain from having a blog. Twenty-three older adult bloggers (aged 60–83 years; most of them with college degrees and retired) from Spain who, at the time of the study had an active blog were interviewed. A thematic analysis identified four different benefits related to blogging: (1) a general sense of satisfaction from producing the blog; (2) relational benefits; (3) cognitive benefits; and (4) identity benefits. Results showed that adults and older people experienced a variety of benefits that broadens the distinction between personal and social benefits found in previous research. Blogging in later life challenges the traditional passive/consumer and online user experience view of adults and older people and seems to be a good example of proactive participation through websites.
