Although studies justify the notion that people often do not contribute to online communities, some research shows that older adults are more likely to participate in online communities than younger people because different generations tend to use the internet differently. For example, "older adults are more likely to seek health information, make purchases, and obtain religious information, but less likely to watch videos, download music, play games, and read blogs online". This is perhaps due in part to the fact that some online communities cater to older generations. The content of the website often determines what age group will use or visit the site, and because many forms of online communities appear on sites that focus their attention on older adults, participation is generally higher. Additionally, the ease and availability of operating the websites that host the online community may play a role in the age group that is most likely to participate. For example, some online communities geared toward older adults have simplified the design of their sites in order to enhance their look and usability for older adults.
