First-order effects

• MySpace users get an events tool that finally leverages friend connections for invitations and discovery, but it enters a market where Evite owns RSVPs and Facebook already ties events directly into the feed users check daily.
• The product is explicitly experimental — a sign that MySpace is shipping defensively to plug feature gaps rather than from a position of strength.

Second-order effects

• Evite, the standalone incumbent, faces pressure to add social-graph features of its own or risk being disintermediated by networks where event planning happens inside the same site people already use socially.
• Facebook needs no response here — its advantage is structural, since events built into an active feed compound network effects that a bolted-on MySpace page can't easily replicate.

Third-order effects

• If the pattern holds, the market consolidates around platforms where the social graph is native infrastructure rather than an add-on, pushing single-purpose tools like Evite toward acquisition, niche focus, or decline.
• It illustrates a durable lesson in platform competition: copying surface features without matching the underlying graph dynamics rarely reverses momentum once a leader has locked in engagement.
