This is the usage that the owners of the trademarks fear (and object to) because substantial usage of that type constitutes a generic use of their trademarks, which could be grounds for being forced to forfeit the trademark.

I have never heard "Facebook" used as a verb ("to facebook").
Photoshop means "edit a photograph", and Google means "search the web".
Facebook provides too many diverse functions to be easily verbed.
Would the verb be transitive or intransitive (e.g. "I facebooked all day" vs "I'll facebook you")?
In the former case, does it mean "update my profile", "look at friends pictures" or "search for new friends"...?
In the latter case, does it mean "add as friend", "send a message", "write on the wall", "ping"...?
It is unclear.
There is no single defining activity that Facebook is used for or a clear result it produces.
Similarly, spreadsheet or database program names ("1-2-3", "Excel", "Oracle", "MySql") are rarely used as verbs.
These programs, like Facebook can be used for diverse tasks.

It doesn't really replace any other verb.
Think of it like "skiing," which means the act of using skis.
I would say that (for the present day, at least) all of these terms still pertain to the act of using the specific item to which they refer.
Some people do say "Google that with Bing," but this is just to satirize the usage of "Google" as a verb.

I've heard my students say, "I'll facebook you" many times.
Of course, what they mean is, "I'll send you a message on Facebook."

Using trademarks as verbs is almost always discouraged by the trademark holder, as it risks genericizing the trademark.
This is why, for example, Microsoft never describes a PowerPoint presentation as "a PowerPoint", but uses the generic term "slideshow".

I understand that any term, grammatical or not, becomes valid if there is common usage. I'm not concerned about that. Google and Photoshop are both commonly used as verbs. Given that the terms map fairly well to verbs (web searching and image editing), I can follow the logic of their use. Does this work for Facebook, though? What verb is it replacing?
Is "facebook" as a verb different from "google" or "photoshop"?
