Twitter may not be best place for startups to look for funding, but it does offer other services. Free advice, for instance, from some of the Web-friendly investors, via the just-launched VCtips.

VCtips is a Twiter bot -- a Twitter feed with multiple authors -- created by Union Square Ventures' Fred Wilson and O'Reilly AlphaTech Vventures' Bryce Roberts. The two of them, along with 8 other VCs, use the service to offer advice and aphorisms, fortune cookie-style, to startups. Like:

if you're not funny, don't use humor in your pitch. vc meetings aren't the best venue for trying out new material.

Here is the roster of other advice-givers. We gather that the list will be growing in the days to come:

Josh Kopelman, First Round Capital
Chris Sacca, former Google exec-turned angel
Rob Hayes, First Round
David Hornik, August Capital
Andy Weissman, Betaworks
Bijan Sabet, Spark Capital
Albert Wenger, USV
Aydin Senkut, Felcis Ventures
