The document discusses how identity is constructed online through various platforms. It compares personal homepages and blogs as ways individuals fashion public identities on the web. Personal homepages in the late 1990s presented fairly static, self-contained identities through individually authored HTML pages. In contrast, blogs allow for more fluid, distributed identities through constantly updated content stored across a database, not confined to a single page. Blogs support a more unruly, multifaceted online social identity than early personal homepages.
